What Are the Rights of a Foreigner Detained by the Police in Türkiye?

Being stopped, arrested or detained by the police in a foreign country can be extremely stressful.

A foreign national in Türkiye may not speak Turkish, may not understand why the police are taking them to a police station and may not know whether they are:

• merely being asked to provide identification;
• formally arrested;
• placed in police custody;
• being questioned as a suspect;
• being taken before a prosecutor;
• being referred to a criminal judge;
• or being transferred into immigration-related administrative detention.

These situations are legally different.

A foreign national who becomes a criminal suspect in Türkiye has important procedural rights under the Turkish Constitution, Criminal Procedure Code No. 5271 and the Regulation on Arrest, Police Custody and Taking Statements.

The person’s nationality does not remove these rights.

Among the most important protections are:

• the right to be informed why they were arrested;
• the right to know the allegation against them;
• the right to remain silent;
• the right to a criminal defence lawyer;
• the right to meet privately with a lawyer;
• the right to have a lawyer present during questioning;
• the right to an interpreter if they cannot adequately communicate in Turkish;
• the right to have a relative or another designated person informed;
• special notification rights concerning the person’s consulate;
• the right to medical examination in the circumstances prescribed by law;
• protection against torture, coercion, threats and improper interrogation techniques;
• the right to challenge arrest and police custody before a judge;
• the right not to be held beyond statutory custody periods without judicial authority;
• and, in qualifying cases, the right to compensation for unlawful deprivation of liberty.

A foreigner should therefore not assume:

“I am not a Turkish citizen, so the police can do anything they want.”

That is incorrect.

Article 19 of the Turkish Constitution begins with a broad guarantee that everyone has the right to personal liberty and security and imposes legal limits on arrest and deprivation of liberty.

Short Answer: What Should a Foreigner Do Immediately After Being Detained in Türkiye?

If a foreign national is taken into police custody, the safest immediate approach is generally to:

1. remain calm and do not physically resist;
2. ask why you have been arrested or detained;
3. request a lawyer immediately;
4. state clearly that you require an interpreter if you do not fully understand Turkish;
5. do not sign a Turkish statement you do not understand;
6. remember that you have the right to remain silent concerning the alleged offence;
7. request notification of a relative or designated person;
8. consider consular notification;
9. tell the authorities and doctor about any injury, illness or medication;
10. inform your lawyer immediately if you believe the arrest or custody is unlawful.

The most important practical rule is:

Do not give a detailed criminal statement simply because you feel pressured to “explain everything quickly” before receiving legal advice and proper interpretation.

What Is the Difference Between Arrest, Police Custody and Pre-Trial Detention in Türkiye?

These terms are often confused by foreign clients.

In Turkish criminal procedure, three important concepts should be distinguished.

1. Arrest — “Yakalama”

Arrest is the initial deprivation of the person’s physical freedom.

For example, police may stop a suspect at:

• an airport;
• hotel;
• home;
• workplace;
• road checkpoint;
• or public place

and state that the person must accompany officers.

The Regulation on Arrest, Police Custody and Taking Statements requires police to inform the arrested person of:

• the reason for arrest;
• allegations against them;
• the right to remain silent;
• the right to legal assistance;
• the right to challenge the arrest;
• and other statutory rights.

2. Police Custody — “Gözaltı”

An arrested person does not automatically have to remain in custody.

The police inform the Public Prosecutor of the arrest.

If release is not ordered and the statutory requirements exist, the person can be placed in gözaltı, meaning police custody for the criminal investigation.

Under Article 91 of the Criminal Procedure Code, custody requires both:

• that the measure is necessary for the investigation;
• and that concrete evidence exists indicating suspicion that the person committed an offence.

Police custody is temporary.

It cannot be used as punishment.

3. Pre-Trial Detention — “Tutuklama”

Pre-trial detention is fundamentally different.

Police cannot simply decide that a suspect will remain in prison pending trial.

A judicial decision is required.

If prosecutors believe pre-trial detention is necessary, the suspect is brought before the competent criminal judge.

The judge can then decide, depending on the case, to:

• release the suspect;
• impose judicial-control measures;
• or order pre-trial detention if the statutory conditions are satisfied.

The Constitution itself requires judicial control over detention and provides that a person cannot be deprived of liberty beyond constitutional limits without a judge’s decision.

Must the Police Tell a Foreigner Why They Were Arrested?

Yes.

An arrested person must be informed of:

• the reason for the arrest;
• the allegation;
• and their legal rights.

The Constitution provides that arrested or detained persons must be informed promptly of the reasons and accusations against them, in writing where possible or orally where immediate written notification is not possible.

The arrest regulation likewise requires immediate notification of the person’s rights.

A foreign suspect should therefore ask:

“What offence am I suspected of?”

and

“Why am I being detained?”

Does a Foreigner Have the Right to Remain Silent in Türkiye?

Yes.

This is one of the most important rights in Turkish criminal proceedings.

Article 147 of the Criminal Procedure Code requires authorities to tell a suspect that they have the legal right not to make a statement concerning the alleged offence.

This is commonly known as the right to silence.

A suspect is not required to prove innocence during the first police interview.

The prosecution bears the criminal burden.

However, an important distinction exists:

The suspect must answer questions relating to their identity correctly.

Article 147 separately requires identification of the suspect while recognising the right to silence regarding the alleged crime.

Therefore:

“What is your name?”

and

“Did you commit this offence?”

are not legally the same type of question.

Should a Foreigner Use the Right to Silence?

Whether a suspect should answer substantive questions depends on the case.

There is no universal strategy.

In some cases, an immediate explanation may be useful.

For example:

• mistaken identity;
• documentary alibi;
• clear payment records;
• obvious misunderstanding.

In other cases, answering questions before the lawyer sees the available allegations can create serious problems.

The safest principle for a foreign suspect who does not yet understand the case is usually:

request a lawyer and interpreter before giving a detailed statement.

Silence should not be confused with guilt.

It is a statutory defence right.

Does a Foreigner Have the Right to a Lawyer?

Yes.

Article 149 of the Criminal Procedure Code provides that a suspect or defendant may benefit from one or more defence lawyers during every stage of investigation and prosecution.

During the investigation stage, up to three lawyers may be present during questioning.

Most importantly, the law states that the lawyer’s right to:

• meet the suspect;
• remain present during questioning or judicial interrogation;
• and provide legal assistance

cannot be prevented or restricted as a general rule.

This right applies to foreign suspects as well.

Can the Police Question a Foreigner Before Their Lawyer Arrives?

A suspect may choose to make a statement without private counsel where mandatory defence rules do not apply.

However, the suspect can request legal assistance.

Article 147 requires the suspect to be informed that:

• they can choose a lawyer;
• the lawyer can be present during the statement;
• and if the suspect cannot appoint a lawyer and requests legal assistance, a lawyer can be appointed through the bar association.

For serious criminal allegations, giving a substantive statement before obtaining legal advice is rarely advisable.

Can a Foreigner Speak Privately with Their Lawyer?

Yes.

This is particularly important in police custody.

The current Regulation provides that a suspect or defendant can meet a defence lawyer:

• without requiring a power of attorney;
• at any time;
• and in an environment where other people cannot hear the conversation.

Correspondence with the defence lawyer is also protected from ordinary monitoring under the provision.

This means a police officer should not normally stand next to the suspect listening to confidential defence discussions.

Attorney-client confidentiality is an essential component of the defence right.

Does the Lawyer Need a Notarised Power of Attorney to Visit the Foreigner in Police Custody?

Not for the initial criminal defence meeting.

The custody regulation expressly states that a suspect may meet defence counsel without requiring a power of attorney.

This is important in emergencies.

A foreign family may contact a criminal lawyer immediately after learning that someone was arrested.

The lawyer does not first need to wait for the detained person to visit a notary.

Can a Bar Association Lawyer Be Appointed?

Yes, depending on the circumstances.

Article 150 provides that where a suspect states that they cannot appoint a lawyer and requests legal assistance, a defence lawyer may be appointed.

In certain cases, legal representation is mandatory even without a request.

Mandatory defence includes a suspect who:

• is a child;
• is deaf or mute;
• or has a disability making them unable adequately to defend themselves

and does not already have a lawyer.

Mandatory defence also applies where the criminal investigation concerns an offence whose minimum statutory sentence exceeds five years’ imprisonment.

Foreign suspects should nevertheless distinguish between:

a bar-appointed defence lawyer

and

a privately retained criminal lawyer selected by the suspect or family.

Does a Foreigner Have the Right to an Interpreter?

Yes.

Language is one of the most important issues in foreigner criminal cases.

A person who understands only basic Turkish should not assume that this is enough for a criminal statement involving:

• complex accusations;
• technical legal terminology;
• dates;
• money;
• intent;
• or alleged communications.

Article 202 of the Criminal Procedure Code provides interpretation for a suspect, defendant, victim or witness who cannot adequately communicate in Turkish during investigation and prosecution.

Current Turkish courts maintain official interpreter lists under this statutory framework, including for numerous languages.

A foreign suspect should clearly state:

“I do not understand Turkish sufficiently to give a criminal statement. I request an interpreter.”

Can the Police Use the Suspect’s Friend as an Interpreter?

For a formal criminal statement, interpretation should comply with criminal-procedure requirements.

A friend or the opposing party should not simply translate a legally significant statement informally where proper interpretation is required.

This is particularly important where the case involves:

• drugs;
• fraud;
• assault;
• sexual offences;
• financial crimes;
• immigration documents;
• or organised crime.

Accurate interpretation may determine the legal meaning of the entire statement.

Who Pays for the Interpreter?

Interpretation necessary because a criminal suspect or other protected participant cannot understand Turkish is part of criminal procedure.

The Turkish criminal procedure framework does not treat the necessary interpretation of a non-Turkish-speaking suspect as an ordinary private luxury that must simply be waived because the person cannot pay.

2026 judicial interpreter lists continue to be established specifically for criminal proceedings under Article 202.

Should a Foreigner Sign a Turkish Police Statement They Cannot Read?

No.

A suspect should not sign a statement without understanding it.

Before signing, check:

• identity details;
• date;
• location;
• exact allegation;
• currency;
• amount;
• names;
• vehicle plates;
• telephone numbers;
• and every substantive sentence attributed to the suspect.

If the interpreter translated something incorrectly, correction should be requested before signature.

A statement signed during police custody can later become important evidence.

Can Police Force a Foreigner to Confess?

No.

Article 148 of the Criminal Procedure Code contains strict rules concerning interrogation methods.

The suspect’s statement must reflect their free will.

Authorities may not obtain a statement through methods including:

• mistreatment;
• torture;
• drugs;
• exhaustion;
• deception;
• physical force;
• threats;
• or comparable physical or psychological interference.

Nor may authorities promise an unlawful benefit in exchange for a statement.

Statements obtained through prohibited methods cannot be used as evidence even where the suspect purportedly consented.

This protection applies equally to foreigners.

What Is the Importance of Having a Lawyer Present During the Police Statement?

Article 148 contains another very important rule.

A statement taken by police without defence counsel present cannot be used as the basis of a judgment unless the suspect or defendant subsequently confirms that statement before the judge or court.

This is an important safeguard.

However, it should not be interpreted as meaning that giving an inaccurate lawyerless police statement carries no risk.

The statement can still affect:

• the investigation;
• prosecutorial strategy;
• contradictions;
• and subsequent proceedings.

Obtaining legal advice before the statement remains preferable.

Can Police Ask the Same Questions Repeatedly Until the Foreigner Changes Their Statement?

The Criminal Procedure Code limits repeated police questioning concerning the same event.

Article 148 provides that where it becomes necessary to take another statement from the suspect concerning the same incident, that new statement can only be taken by the Public Prosecutor.

This protection is intended to prevent repeated police interrogation from being used improperly.

Does a Foreigner Have the Right to Have Their Family Notified?

Yes.

Article 95 provides that when a suspect or defendant is:

• arrested;
• placed in custody;
• or has the custody period extended,

a relative or another person selected by the suspect must be informed without delay on the order of the Public Prosecutor.

Article 147 also includes notification rights among the rights to be explained to the suspect.

For a foreigner, this may be especially important because family members may need to:

• contact a lawyer;
• obtain passport documents;
• notify an employer;
• arrange medication;
• or contact the consulate.

Does a Foreigner Have the Right to Consular Notification?

Yes, there is a specific statutory rule for foreigners.

Article 95/2 of the Criminal Procedure Code provides:

Where the arrested or detained person is a foreign national, the situation is notified to the consulate of the State of which the person is a citizen unless the foreigner objects in writing.

The arrest regulation contains the same principle.

This is a significant protection for foreign nationals.

The consulate may potentially assist with matters such as:

• confirming identity;
• communicating with family;
• providing general information;
• or following the welfare of the national.

However, the consulate is not a substitute for a Turkish criminal defence lawyer.

Should a Foreigner Always Ask the Consulate to Be Informed?

Not necessarily.

It depends on the person’s circumstances.

Some foreign nationals may specifically prefer that their government not be notified.

Turkish law recognises this by allowing the foreigner to object in writing to notification.

The decision should be considered carefully.

Does a Foreigner Have a Right to Medical Examination?

Yes, in the circumstances provided by the custody regulation.

The Regulation requires medical examination when:

• an arrested person is going to be placed in police custody;
• force was used during arrest;
• the place of detention changes;
• custody is extended;
• the person is released;
• or the person is transferred to judicial authorities.

The person’s condition is documented through a medical report.

If the person’s health deteriorates or there is suspicion concerning their health, they must be taken for medical examination and necessary treatment.

Why Is the Medical Report Important?

The medical report has two functions.

First, it protects the suspect’s health.

Second, it creates objective evidence concerning physical condition while in custody.

A foreign suspect should tell the doctor about:

• injuries;
• pain;
• bruising;
• difficulty breathing;
• chronic illness;
• diabetes;
• epilepsy;
• heart disease;
• pregnancy;
• psychiatric medication;
• prescription drugs;
• or any other significant condition.

Do not conceal injuries because of fear.

What If the Foreigner Was Injured During Arrest?

The injury should be reported immediately to:

• the doctor;
• lawyer;
• prosecutor;
• and, where necessary, judicial authorities.

The medical report should accurately record physical findings.

If inappropriate force or mistreatment occurred, the lawyer can evaluate:

• criminal complaint;
• evidentiary requests;
• medical documentation;
• CCTV;
• and other legal remedies.

How Long Can a Foreigner Be Kept in Police Custody in Türkiye?

Nationality does not create a longer ordinary custody period.

Under the general rule in Article 91, police custody cannot normally exceed 24 hours from the moment of arrest, excluding the time strictly necessary to transport the person to the nearest judge or court.

That transport period cannot exceed 12 hours.

Police custody must also be necessary for the investigation and supported by concrete evidence indicating criminal suspicion.

Can the 24-Hour Period Be Extended?

Yes, in specified circumstances.

For collectively committed offences, where:

• collecting evidence is difficult;
• or the number of suspects is high,

the Public Prosecutor can issue written extensions.

Each extension cannot exceed one day and the period can be extended for up to three additional days.

The extension order must be notified immediately to the detained person.

In practical terms, this can produce a maximum custody period of up to four days within that statutory collective-offence framework.

Are There Special Custody Rules for Certain Flagrante Delicto Cases?

Yes.

Article 91/4 contains a special framework limited to specified flagrante delicto situations.

For designated offences and certain serious public-order situations, police chiefs identified by administrative authorities may order custody:

• for up to 24 hours;
• and, in certain widespread violent public-order situations and collectively committed offences, for up to 48 hours.

The provision includes specified offences such as certain homicide, assault, sexual, robbery, drug-trafficking, terrorism and smuggling offences.

Where the person is not released, the statute still imposes judicial time limits and requires the case to move into the ordinary prosecutorial framework.

This is an exceptional system and should not be confused with the ordinary 24-hour prosecutor-controlled custody rule.

Does the Constitution Also Set Maximum Limits?

Yes.

Article 19 of the Turkish Constitution provides that, excluding the time required to send the person to the nearest court, an arrested or detained person must be brought before a judge within:

• no more than 48 hours in the constitutional framework for individual cases;
• and no more than four days for collectively committed offences.

No person may remain deprived of liberty beyond the constitutional limits without judicial authority.

These are constitutional ceilings.

They do not mean police are automatically entitled to use the entire maximum period in every case.

Can Police Keep a Foreigner in Custody Simply Because the Maximum Period Has Not Expired?

No.

Custody must remain necessary.

The Constitutional Court has emphasised that custody periods are maximum periods and that a person should not simply remain detained until the clock runs out where the investigation can be completed earlier.

The basic principle is proportionality and necessity.

Can the Foreigner Challenge the Arrest or Custody?

Yes.

Article 91 provides a direct judicial remedy.

The following persons can challenge:

• the arrested person;
• defence lawyer;
• legal representative;
• spouse;
• first-degree blood relative;
• or second-degree blood relative.

An application can be made to the Criminal Judgeship of Peace (Sulh Ceza Hâkimliği) seeking immediate release.

The judge must examine the application promptly and, in any event, within 24 hours.

Can the Lawyer Challenge an Extension of Police Custody?

Yes.

The challenge can concern:

• the arrest;
• decision to place the person in custody;
• or written order extending custody.

Article 91 expressly recognises these remedies.

Possible arguments can include:

• absence of concrete suspicion;
• custody not being necessary for investigation;
• completed investigative procedures;
• disproportionate duration;
• mistaken identity;
• unlawful arrest;
• or improper extension.

What Happens When the Police Custody Period Ends?

The person cannot simply remain indefinitely in a police cell.

At the end of the applicable period, the person must either:

be released

or

be brought into the judicial process.

Article 91 provides that where the detained person is not released, they are brought before the Criminal Judgeship of Peace for questioning at the end of the statutory period.

A defence lawyer must be present during that judicial questioning.

What Can Happen Before the Criminal Judge?

Possible outcomes include:

Release

The suspect may simply be released.

Judicial Control

The person may be released subject to measures such as:

• reporting/signature obligations;
• travel restrictions;
• bail/security;
• or other judicial-control measures allowed by law.

Pre-Trial Detention

Where the statutory conditions exist, the judge can order pre-trial detention.

The prosecutor’s request does not automatically bind the judge.

Is Police Custody the Same as Being “Arrested Until Trial”?

No.

This misunderstanding is particularly common among English-speaking foreigners.

“Gözaltı” is short-term investigative custody.

“Tutuklama” is judicial pre-trial detention.

A person can spend one day in police custody and then be released without ever being placed in pre-trial detention.

Can Police Take the Foreigner’s Phone?

Potentially, depending on the investigation and applicable search/seizure rules.

But police possession of a device does not mean investigators have unlimited legal authority to search every digital record without complying with criminal-procedure requirements.

Digital evidence can raise separate rules involving:

• search;
• seizure;
• examination;
• copying;
• and preservation.

A criminal lawyer should examine the particular decision and procedure.

Can Police Search the Foreigner?

A security search may be performed in connection with arrest for safety purposes.

More intrusive searches and searches of:

• residence;
• hotel room;
• vehicle;
• computer;
• or other property

are subject to their own criminal-procedure rules.

The foreigner should not physically resist an official search.

Any legal challenge should instead be made through the lawyer and judicial process.

Should a Foreigner Give Their Phone Password to Police?

This can involve complex criminal-procedure and digital-evidence issues.

The safest approach in a serious criminal investigation is to obtain advice from defence counsel before voluntarily providing access credentials or consenting to digital examination.

Physical resistance or destruction of evidence should never be attempted.

Does a Foreigner Have the Right to Present Evidence in Their Own Defence?

Yes.

Article 147 requires authorities to remind the suspect that they may request collection of concrete evidence to eliminate suspicion and that they must be given the opportunity to raise circumstances in their favour.

This is often highly important.

For example, a foreign suspect accused of fraud may have:

• bank records;
• contracts;
• messages;
• invoices;
• hotel records;
• flight records;
• CCTV;
• GPS;
• witnesses;
• or company documents

that immediately contradict the allegation.

The lawyer should identify and preserve that evidence quickly.

What If the Foreigner Has an Alibi?

Tell the lawyer immediately.

A good alibi can involve evidence such as:

• passport entry/exit records;
• airline boarding passes;
• hotel records;
• workplace records;
• CCTV;
• card transactions;
• mobile-phone location;
• witnesses;
• or digital records.

Some evidence can disappear quickly.

Do not wait until trial to preserve easily obtainable alibi evidence.

Can Police Tell the Foreigner “If You Confess, You Can Go Home”?

Statements obtained through unlawful promises or coercion raise serious Article 148 issues.

Authorities cannot promise an unlawful benefit in order to obtain a confession.

A suspect should immediately tell their lawyer about any such statement.

What If the Police Tell the Foreigner That a Lawyer Will “Make Things Worse”?

The right to legal assistance belongs to the suspect.

Article 149 states that legal assistance and counsel’s presence cannot generally be obstructed or restricted.

Requesting a lawyer should not be treated as evidence of guilt.

What If the Foreigner Does Not Understand the Interpreter?

Say so immediately.

Interpretation must be meaningful.

For example, two people may technically speak “Arabic” but use very different dialects.

A person may speak conversational English but not enough English to understand technical criminal accusations.

The foreigner should not remain silent merely because an interpreter has technically been appointed.

Say:

“I do not understand this interpreter sufficiently.”

The issue should be recorded.

Can a Foreigner Ask for Their Own Private Interpreter?

The formal criminal statement must comply with statutory interpretation procedures.

A privately instructed interpreter may assist communication with counsel in appropriate contexts, but the official criminal-procedure translation must meet judicial requirements.

The lawyer should coordinate this where necessary.

Does a Foreigner Have the Right to Food, Water and Basic Needs During Custody?

Custody is not a punishment and the detained person remains entitled to humane treatment.

Conditions of detention are subject to constitutional, statutory and human-rights protections.

Health problems or denial of essential needs should be immediately communicated to:

• custody officers;
• doctor;
• prosecutor;
• and lawyer.

Can Handcuffs Be Used?

The fact that a person is arrested does not mean unnecessary force is permitted.

Police can take measures necessary to:

• prevent escape;
• prevent harm;
• and ensure security.

The proportionality of the measure depends on the circumstances.

A foreigner should not physically resist but should tell their lawyer if force appears unnecessary or caused injury.

What If Police Use Violence?

Tell the examining doctor immediately.

Ask that every injury be documented.

Tell defence counsel.

Preserve:

• photographs;
• medical records;
• witness names;
• custody location;
• officer information if known;
• and CCTV details.

Potential criminal and constitutional remedies may arise.

Can a Foreigner Be Arrested at the Airport Because of an Old Turkish Case?

Yes.

An existing:

• arrest warrant;
• apprehension order;
• criminal conviction;
• or other judicial order

may become visible during border-control procedures.

The legal response depends on what type of warrant exists.

In some cases, a person arrested under a warrant for the purpose of obtaining a statement can potentially be processed through special rules concerning appearance before the issuing authority.

Article 94 contains procedural mechanisms for persons arrested under judicial warrants.

What If the Foreigner Does Not Know About the Turkish Criminal Case?

The lawyer should determine:

• prosecutor file;
• court;
• case number;
• alleged offence;
• warrant type;
• date;
• and procedural stage.

The fact that the foreigner was unaware of the case does not automatically make the warrant invalid.

But service and defence-right issues may become relevant.

Does Being Detained Automatically Cancel a Residence Permit?

No.

A criminal arrest or custody measure and immigration status are legally separate matters.

Being questioned as a suspect does not by itself mean:

• the person is guilty;
• their residence permit automatically disappears;
• or they are automatically deported.

However, depending on the offence and immigration circumstances, criminal proceedings may later trigger a separate assessment by migration authorities.

That process must be analysed under immigration law.

Can a Foreigner Be Released from Criminal Custody but Then Taken to a Removal Centre?

Yes, potentially.

This distinction is extremely important.

A foreigner may be released from criminal police custody but then become subject to a separate immigration procedure.

Under the Foreigners and International Protection Law No. 6458, a foreigner falling within the deportation framework can be reported to the governorate, and a separate administrative detention decision can be made where statutory conditions exist. Foreigners under administrative detention for deportation are held in Removal Centres.

Therefore:

criminal release does not always mean immediate physical freedom from all immigration measures.

Is Immigration Administrative Detention the Same as Police Custody?

No.

They are entirely different legal procedures.

Criminal Custody

Governed primarily by the Criminal Procedure Code.

Purpose:

investigation of an alleged criminal offence.

Immigration Administrative Detention

Governed primarily by Law No. 6458.

Purpose:

immigration and deportation procedures.

Under current immigration law, qualifying administrative-detention decisions can be challenged before the Criminal Judgeship of Peace, and the judge must examine the application within five days.

A criminal lawyer representing a foreign suspect should therefore check whether an immigration issue exists before assuming that release from the prosecutor’s office ends the matter.

Can the Foreigner Contact a Lawyer from a Removal Centre?

Yes.

Law No. 6458 expressly provides access in Removal Centres to:

• relatives;
• legal representatives;
• lawyers;
• telephone services;
• and consular officials.

But this is an immigration-law procedure separate from criminal police custody.

Can an Arrested Foreigner Be Deported Before the Criminal Case Ends?

This depends on:

• criminal case status;
• judicial restrictions;
• immigration decision;
• alleged offence;
• public-order assessment;
• travel restrictions;
• and other circumstances.

There is no universal answer.

A person can have both:

criminal proceedings

and

deportation proceedings

at the same time.

They should be defended separately.

What Should a Family Member Do If a Foreigner Has Been Arrested in Türkiye?

A family member should obtain:

• full legal name;
• passport number;
• nationality;
• date of birth;
• police station;
• city;
• approximate arrest time;
• alleged offence if known;
• and contact details of witnesses.

Then contact a Turkish criminal lawyer.

The lawyer can attempt to determine:

• police unit;
• prosecutor’s office;
• investigation number;
• whether the person is formally in custody;
• whether questioning has begun;
• and whether the person will be sent to court.

Should the Family Call the Consulate?

This may be useful, particularly where:

• the foreigner has no local family;
• passport problems exist;
• communication is difficult;
• or welfare concerns arise.

But the consulate does not replace criminal defence counsel.

Practical Example 1: Foreign Tourist Arrested After a Fight

A British tourist becomes involved in a fight outside a nightclub.

Police arrest several people.

The tourist does not speak Turkish.

The tourist has the right to:

• be informed of the accusation;
• receive interpretation;
• request a lawyer;
• remain silent on the alleged offence;
• have a selected person informed;
• receive medical examination where required;
• and challenge unlawful custody.

If the tourist has injuries, they should be documented immediately.

Practical Example 2: Foreigner Accused of Drug Possession

A foreign tourist is stopped in a vehicle where police find narcotics.

Several passengers are arrested.

The foreigner states that the drugs are not theirs.

Immediate legal issues include:

• location of drugs;
• possession/control;
• fingerprints or forensic evidence;
• statements of other occupants;
• search procedure;
• and the difference between personal use and trafficking allegations.

The foreign suspect should request a lawyer before giving a detailed statement.

Practical Example 3: Foreigner Accused of Online Fraud

A foreign national’s Turkish bank account received money from an alleged scam.

The foreigner says:

“I gave access to my account to another person.”

The investigation may concern:

• knowledge;
• intent;
• account access;
• onward transfer;
• commission;
• IP/device evidence;
• and communications.

A premature statement without understanding bank records could be damaging.

Practical Example 4: Foreign Businessperson Arrested at Istanbul Airport

A foreign executive arrives at Istanbul Airport.

Passport control reveals an old arrest warrant arising from a commercial criminal complaint.

The person is arrested.

A lawyer should immediately determine:

• which prosecutor/court issued the warrant;
• purpose of the warrant;
• alleged offence;
• whether only a statement is required;
• and whether the person will be transferred to another city.

The person still has the right to counsel and interpretation.

Practical Example 5: Foreigner Cannot Understand Police Interpreter

A Russian-speaking foreigner is provided with an interpreter who speaks a language variant the suspect cannot adequately understand.

The suspect should state this immediately.

The lawyer should request that the problem be recorded and that competent interpretation be provided before questioning continues.

Practical Example 6: Police Ask the Foreigner to Sign a Prepared Statement

A foreign suspect is shown a Turkish document and told:

“Sign it; it just says that we informed you of your rights.”

The document actually contains a substantive statement.

The foreigner should not sign before the document has been properly interpreted and checked.

Practical Example 7: Foreigner Is Released but Taken to a Removal Centre

A foreign suspect is released by the prosecutor.

Police then state that the person will be transferred to immigration authorities.

This is no longer simply a criminal-custody question.

The lawyer should immediately determine whether:

• a deportation decision exists;
• administrative detention has been ordered;
• and a Criminal Judgeship of Peace application is required under Law No. 6458.

Practical Example 8: Custody Is Unnecessarily Extended

Police complete the suspect’s statement and all essential investigation procedures quickly.

Nevertheless, the person remains in custody despite no continuing investigative necessity.

Article 91 requires custody to be necessary for the investigation.

The Constitutional Court also stresses that statutory time periods are maximum periods, not automatic detention entitlements.

The lawyer can consider an immediate judicial challenge.

Can a Foreigner Claim Compensation for Unlawful Arrest or Police Custody?

Potentially, yes.

Turkish law provides compensation mechanisms for unlawful criminal-procedure protective measures.

The Constitution expressly states that damages caused by deprivation-of-liberty measures applied contrary to Article 19 principles are compensated by the State according to general compensation principles.

Article 141 of the Criminal Procedure Code also identifies circumstances in which compensation may be claimed.

These can include certain cases involving:

• unlawful arrest or detention;
• failure to bring a person before a judge within legal time;
• failure to inform the person of rights;
• failure to make required notifications;
• and situations where the person is arrested/detained and the case subsequently ends with qualifying non-prosecution or acquittal outcomes.

Did the Compensation Procedure Change?

Yes.

This is an important current-law point.

Law No. 7499, which entered into force in March 2024, changed the procedural allocation of some CMK compensation claims.

Claims falling specifically within CMK Article 141/1(e), (f) and (l) are now handled under the legislation governing the Human Rights Compensation Commission.

The Ministry of Justice confirms that applications concerning these categories can be made to the Compensation Commission under the expanded system from 1 June 2024.

Other CMK 141 compensation claims can remain within the Article 142 court procedure.

Therefore, a person seeking compensation should not rely on old internet articles stating simply:

“Every unlawful custody compensation claim is filed at the Heavy Criminal Court.”

Since 2024, the exact statutory ground determines the competent compensation route.

Can Someone Receive Compensation If They Are Ultimately Acquitted?

Potentially.

One of the compensation grounds concerns persons who were arrested or detained and subsequently received:

• a decision of no ground for prosecution;
• or acquittal,

subject to the applicable statutory framework.

The Constitutional Court has also examined the adequacy of compensation awarded for custody followed by acquittal and has emphasised that compensation must not be merely symbolic when a constitutional violation exists.

Does Acquittal Automatically Mean the Police Acted Unlawfully at the Time?

Not necessarily.

A custody measure can have appeared lawful based on information available at the time even where the case later ends in acquittal.

However, the Turkish compensation framework expressly provides compensation rights in specified post-acquittal/non-prosecution circumstances without requiring every case to be analysed purely as an initially unlawful arrest.

This distinction is technical but important.

Frequently Asked Questions

Can Turkish police arrest a foreign tourist?

Yes, where Turkish law permits arrest.

Foreign nationality does not provide immunity from Turkish criminal law.

Yes. Article 149 protects a suspect’s access to defence counsel throughout the criminal proceedings.

Can I ask for a lawyer before speaking to the police?

Yes.

Can I remain silent?

Yes concerning the alleged offence. You must nevertheless answer identity questions correctly.

Will my consulate be informed?

For a foreign detainee, the consulate of the person’s State is notified unless the foreigner objects in writing.

Can I refuse consular notification?

Yes, by written objection under the statutory framework.

How long can ordinary police custody last?

The general Article 91 rule is 24 hours from arrest, excluding necessary transfer time of up to 12 hours.

Can this be extended?

For collectively committed offences, the prosecutor may issue one-day extensions up to three additional days where statutory requirements exist.

Can the police keep me for the full period even after investigation is finished?

Custody must remain necessary. Statutory periods are maximum periods rather than automatic entitlements.

Can I challenge police custody?

Yes. Article 91 provides an application to the Criminal Judgeship of Peace seeking immediate release.

How quickly must the judge decide that application?

The Article 91 framework requires a decision immediately and no later than 24 hours.

Does police custody mean I will be sent to prison?

No. You can be released. Pre-trial detention requires a judicial decision.

Can police release me after questioning?

Yes.

Can I be released from criminal custody but sent to a Removal Centre?

Potentially yes if an independent immigration administrative-detention procedure exists.

Is a Removal Centre the same as police custody?

No. Removal-centre detention is immigration administrative detention governed primarily by Law No. 6458.

Can administrative detention be challenged?

Yes. The foreigner, legal representative or lawyer may apply to the Criminal Judgeship of Peace.

Can a foreigner receive compensation for unlawful detention?

Potentially yes under the Constitution and CMK compensation provisions.

What Should a Foreigner Never Do While in Police Custody?

Several mistakes can seriously damage the defence.

Do Not Physically Resist

Even if you believe the arrest is unlawful, physical resistance can create:

• additional allegations;
• injury;
• and evidentiary problems.

Challenge legality through counsel.

Do Not Sign What You Do Not Understand

This is particularly important for foreign-language suspects.

Do Not Guess

If you do not remember something, say so.

Do not invent an answer because officers expect one.

Do Not Delete Digital Evidence

Deleting messages or destroying devices can create serious problems.

Do Not Ask Another Person to Hide Evidence

This can create separate criminal allegations.

Do Not Assume Informal Conversation Is Meaningless

Statements made around police personnel may later become relevant.

Do Not Waive a Lawyer Simply to “Finish Faster”

A short interview can have long-term consequences.

What Information Should Be Given to the Criminal Lawyer?

The detained person or family should provide:

• full name;
• nationality;
• passport number;
• date of birth;
• police station;
• arrest location;
• arrest time;
• alleged offence;
• whether a search took place;
• whether phones or money were seized;
• whether a statement has already been given;
• interpreter language;
• known prosecutor file;
• existing medical issues;
• and immigration/residence status where relevant.

Time matters.

What Can a Criminal Lawyer Do During Police Custody?

A lawyer may:

• locate the suspect;
• meet the suspect confidentially;
• learn the nature of the allegation within applicable investigation rules;
• advise whether to remain silent or give a statement;
• attend the statement;
• ensure interpretation problems are recorded;
• identify favourable evidence;
• request preservation of evidence;
• challenge arrest or custody;
• monitor medical examination issues;
• attend judicial questioning;
• argue against pre-trial detention;
• propose judicial-control alternatives;
• and coordinate immigration representation if necessary.

For a foreign suspect, the combination of criminal and immigration law can make early legal intervention particularly important.

Conclusion: A Foreigner Detained by Police in Türkiye Has Important Rights from the First Moment of Arrest

A foreign national who is arrested by police in Türkiye does not lose basic legal protections because of nationality.

The Turkish Constitution protects the personal liberty and security of everyone, not only Turkish citizens.

From the first moment of arrest, the foreign suspect must be treated according to criminal-procedure rules.

The person should be informed:

• why they were arrested;
• what offence they are suspected of;
• and what legal rights they possess.

The first critical right is the right to remain silent.

Article 147 requires the suspect to be told that they are not obliged to make a statement concerning the alleged offence. At the same time, the suspect must provide accurate identifying information.

The second critical protection is the right to a defence lawyer.

Article 149 allows the suspect to receive legal assistance throughout investigation and prosecution and protects the lawyer’s ability to:

• meet the suspect;
• attend questioning;
• attend judicial interrogation;
• and provide legal assistance.

The detained foreigner can meet counsel without first producing a notarised power of attorney and the consultation must occur in a setting where others cannot hear the conversation.

The third major right is interpretation.

A foreigner should never give a criminal statement in a language they cannot understand sufficiently.

Criminal cases can turn on subtle distinctions such as:

“I knew”

versus

“I suspected”

or

“I received the money”

versus

“the money entered an account that another person controlled.”

A poor translation can therefore change the entire criminal meaning of a statement.

Article 202 provides interpretation safeguards for persons who cannot adequately communicate in Turkish, and Turkish judicial authorities maintain interpreter lists for criminal proceedings.

The fourth important right concerns family and consular notification.

Article 95 requires notification of a relative or person selected by the detained suspect.

For foreign nationals, there is an additional rule: unless the foreigner objects in writing, the situation is notified to the consulate of the country of nationality.

The fifth important protection is medical examination.

The arrest and custody regulation requires medical documentation in several important stages, including entry into custody and release or transfer, and requires immediate examination where health deteriorates.

The sixth protection concerns interrogation methods.

The suspect’s statement must reflect free will.

Turkish law expressly prohibits obtaining statements through:

• torture;
• mistreatment;
• exhaustion;
• medication;
• threats;
• force;
• deception;
• or improper promises.

Statements obtained through such methods cannot lawfully be treated as evidence.

The seventh protection concerns time.

Under the ordinary Article 91 rule, police custody generally cannot exceed 24 hours from arrest, excluding strictly necessary transfer time of no more than 12 hours.

In collectively committed offences, written prosecutorial extensions of up to one day each may be ordered for a maximum of three additional days where the statutory reasons exist.

Special flagrant-offence provisions exist for certain serious offences and public-order situations, but these do not create unlimited police detention.

The Constitution itself establishes judicial limits on deprivation of liberty.

Most importantly, these periods are maximum limits.

They are not permission to keep a person in a cell unnecessarily after relevant investigation procedures are complete.

The Constitutional Court has emphasised that custody must remain justified by actual investigative necessity.

The eighth protection is judicial review.

A foreign detainee does not simply have to wait for the custody period to expire.

Article 91 allows:

• the detainee;
• lawyer;
• legal representative;
• spouse;
• or specified close relatives

to apply to the Criminal Judgeship of Peace challenging arrest, custody or extension and seeking immediate release.

The judge must review the application promptly and within 24 hours.

Foreign suspects must also understand one additional complication.

Criminal custody and immigration detention are not the same thing.

A foreign person may be released from the criminal investigation yet still face a separate immigration decision.

Under Law No. 6458, immigration authorities may impose administrative detention for deportation purposes where specific statutory grounds exist.

Such foreigners may be transferred to a Removal Centre, and that administrative detention can be separately challenged before the Criminal Judgeship of Peace.

Therefore, when a foreigner is detained in Türkiye, the lawyer should ask two separate questions:

What is happening in the criminal investigation?

and

Is there also an immigration or deportation process?

Finally, unlawful deprivation of liberty can create compensation rights.

The Constitution guarantees compensation where liberty is restricted contrary to its safeguards, while Articles 141 and following of the Criminal Procedure Code create detailed compensation mechanisms.

The procedure changed significantly in 2024.

Some compensation claims—specifically those within CMK 141/1(e), (f) and (l)—are now handled through the Human Rights Compensation Commission under the expanded Law No. 6384 framework, while other claims remain within the criminal-court compensation procedure.

Accordingly, old articles saying every wrongful-detention compensation claim must automatically be filed before a Heavy Criminal Court are no longer fully accurate.

For a foreign person detained by Turkish police, the most important practical rules can therefore be summarised in ten sentences:

Ask why you were arrested.

Request a Turkish criminal lawyer.

Request an interpreter if your Turkish is not fully sufficient.

Remember your right to remain silent about the alleged offence.

Do not sign a statement you do not understand.

Request family and, where desired, consular notification.

Report every health condition or injury during the medical examination.

Do not accept threats, coercion or unlawful interrogation methods.

Have your lawyer check the legal custody deadline and challenge custody when necessary.

If you are released from criminal custody, confirm whether any separate immigration detention or deportation procedure exists.

Early action matters because the first hours of a criminal investigation can determine:

• what statement is recorded;
• what evidence is preserved;
• whether the person remains in custody;
• whether pre-trial detention is requested;
• and whether a separate immigration process begins.
