Introduction

Being arrested or detained in a foreign country can be an extremely stressful experience.

A foreign national in Turkey may suddenly find themselves dealing with police officers, prosecutors, translators, criminal courts and legal terminology they do not understand.

This can happen to:

• tourists;
• expatriates;
• foreign employees;
• international students;
• foreign company executives;
• foreign property owners;
• investors;
• persons travelling through Turkish airports; or
• foreigners living permanently in Turkey.

A foreign national may be investigated in Turkey in connection with allegations involving:

• assault;
• traffic accidents;
• drugs;
• theft;
• fraud;
• cybercrime;
• financial offences;
• sexual offences;
• document fraud;
• customs offences;
• smuggling;
• public-order offences;
• terrorism-related allegations; or
• other crimes under Turkish law.

The first hours after an arrest can have a major effect on the entire criminal investigation.

Statements may be taken.

Mobile phones may be seized.

Digital evidence may be examined.

Witnesses may be interviewed.

The prosecutor may request detention.

The suspect may later be taken before a Criminal Judgeship of Peace — Sulh Ceza Hâkimliği for a decision on arrest, judicial control or pre-trial detention.

For foreign nationals, an additional layer of complexity exists because a criminal investigation can also affect immigration status.

A criminal case may potentially lead to:

• cancellation of a residence permit;
• problems with a work permit;
• an entry restriction;
• a restriction code;
• deportation proceedings; or
• an entry ban.

However, foreign nationality does not eliminate the fundamental procedural rights granted to suspects and defendants under Turkish law.

The principal legislation is Criminal Procedure Code No. 5271 — Ceza Muhakemesi Kanunu (CMK).

Among the most important rights are:

• the right to know the accusation;
• the right to remain silent;
• the right to a lawyer;
• the right to consult a lawyer privately;
• the right to an interpreter;
• the right to consular notification;
• the right to request collection of evidence in one’s favour;
• protection against torture and coercive interrogation;
• the right to challenge unlawful custody; and
• the right to judicial review of pre-trial detention.

Turkish Constitutional law also protects the presumption of innocence. A person accused of a criminal offence remains legally innocent unless guilt is established through a final criminal judgment. The Turkish Constitutional Court describes this principle as requiring public authorities to refrain from treating a person as guilty before a final conviction.

For a foreign national arrested in Turkey, the most important practical rule is therefore:

Do not confuse cooperation with giving an immediate substantive statement before understanding the accusation and obtaining legal advice.

Arrest, Police Custody and Pre-Trial Detention Are Different

English-speaking foreigners frequently use the word “arrest” to describe several different Turkish criminal procedure measures.

Turkish law distinguishes between:

Yakalama — apprehension/arrest

Gözaltı — police custody

and

Tutuklama — judicial pre-trial detention

These measures are legally different.

What Is Yakalama?

Yakalama is the initial act of taking a person under physical control.

Under Article 90 of the Criminal Procedure Code, apprehension may occur in circumstances including situations where:

• a person is caught while committing an offence;
• a person is being pursued immediately following a flagrante delicto offence and there is a risk of escape; or
• police have authority to apprehend a person in urgent circumstances connected with a warrant or circumstances justifying judicial intervention.

Once the police apprehend the person, they must take measures to prevent escape or harm and must immediately inform the person of their legal rights.

An apprehended foreigner should therefore be informed that they are being treated as a suspect and should be told the legal basis for the procedure.

What Is Police Custody — Gözaltı?

Being apprehended does not necessarily mean that the person will remain in custody.

After the police inform the prosecutor, the prosecutor may:

• order release;
• request further investigative steps; or
• order that the suspect be placed in police custody.

Article 91 provides that custody must be necessary for the criminal investigation and must be based upon concrete evidence creating suspicion that the person committed an offence.

Therefore, police custody is not supposed to be used simply because a person is foreign or because an allegation has been made.

There must be a legally relevant criminal investigation.

How Long Can a Foreigner Be Held in Police Custody in Turkey?

The ordinary rule under Article 91 is that police custody cannot exceed:

24 hours from the moment of apprehension, excluding the legally permitted transportation period necessary to bring the person before the nearest judge or court.

The transportation period cannot exceed 12 hours.

For offences allegedly committed collectively, the prosecutor may extend custody because of difficulty in collecting evidence or the number of suspects.

Each extension can be for no more than one day, and the ordinary collective-offence mechanism permits extensions of up to three additional days. The extension order must be in writing and notified to the detained person.

There are also special custody rules for certain flagrante delicto offences, serious public-order incidents, terrorism-related matters and other categories expressly listed in Article 91.

Accordingly, a foreign national should not rely on the general statement:

“Police can only keep me for 24 hours in every case.”

The applicable period depends upon the nature of the investigation and the statutory procedure being used.

However, custody is never unlimited.

If the suspect is not released within the applicable period, the person must ultimately be brought before the competent judicial authority. Article 91 expressly provides that where the detained person is not released, the suspect is brought before the Criminal Judgeship of Peace for questioning and the defence lawyer is present.

Can Police Custody Be Challenged?

Yes.

Article 91 permits the apprehended person, defence lawyer, legal representative, spouse or qualifying close relatives to challenge:

• the apprehension;
• the custody decision; or
• an extension of custody

before the Criminal Judgeship of Peace.

The purpose of this application is to obtain immediate release.

The judge must review the challenge promptly and generally no later than twenty-four hours.

This can be particularly important where:

• there is no sufficient evidence;
• the wrong person has been apprehended;
• identity has been confused;
• custody is no longer necessary;
• the detention period has been incorrectly calculated; or
• there is another procedural illegality.

What Rights Must Police Explain to a Foreign Suspect?

Under Turkish criminal procedure, the suspect must be informed of fundamental rights.

Article 147 provides that before a substantive statement or judicial questioning, the suspect must be informed of matters including:

• the accusation;
• the right to choose a defence lawyer;
• the right to receive legal assistance;
• the right to have a lawyer present;
• the right to have an appointed lawyer where applicable;
• the right to remain silent;
• the right to request collection of concrete evidence in their favour; and
• the opportunity to present matters capable of removing suspicion.

These are not optional courtesies.

They form part of the formal safeguards surrounding a criminal statement.

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

Yes.

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

Article 147 expressly requires that a suspect be told that they have a legal right not to make a statement concerning the alleged offence.

The foreign suspect is required to provide accurate information concerning identity.

But answering questions about identity should be distinguished from giving a substantive criminal statement concerning:

• what happened;
• why the person was present;
• who owned an item;
• whose money was involved;
• who sent a message;
• why a transaction occurred;
• whether drugs belonged to the suspect;
• whether the suspect knew another person; or
• other facts relating to the alleged offence.

A suspect may exercise the right to remain silent on the substance of the allegation.

Should a Foreign Suspect Give a Statement Immediately?

There is no single answer for every criminal case.

Sometimes an early statement can be extremely useful.

For example, immediate documentary evidence may establish:

• mistaken identity;
• an alibi;
• lawful ownership;
• a legitimate business transaction;
• lack of knowledge;
• lawful medical possession;
• absence from the crime scene; or
• another fact capable of ending the investigation quickly.

In another case, an unprepared statement may create serious problems because:

• the foreigner does not fully understand the accusation;
• police have more evidence than the suspect knows;
• translation is inaccurate;
• the suspect is exhausted;
• the chronology is complicated;
• digital transactions require technical explanation;
• another suspect has made contradictory allegations; or
• the person inadvertently confirms an element of an offence.

The safest general principle is therefore:

Understand the accusation, speak privately with a Turkish criminal defence lawyer and then decide whether a substantive statement should be given.

The right to remain silent exists precisely because a suspect should not be forced to build the prosecution’s case against themselves.

Does a Foreigner Have the Right to a Lawyer in Turkey?

Yes.

A foreign suspect has the same basic right to criminal defence assistance as a Turkish suspect.

Article 149 permits a suspect or defendant to benefit from one or more defence lawyers throughout the investigation and prosecution.

Article 150 additionally provides mechanisms for appointment of a lawyer where the suspect cannot choose one and requests legal assistance. A lawyer must be appointed automatically in certain cases, including specified vulnerable suspects and investigations involving offences with sufficiently serious statutory minimum imprisonment.

Foreign nationality does not reduce this right.

Can the Police Refuse to Allow a Lawyer Into the Interview?

As a general principle, the defence lawyer’s right to provide legal assistance during the criminal process cannot simply be ignored.

Article 149 provides that the lawyer may:

• meet the suspect;
• be present during the statement;
• be present during judicial questioning; and
• provide legal assistance throughout the investigation and trial.

There are exceptional statutory rules affecting access to a lawyer in limited categories of serious offences.

For specified offences, including certain terrorism and organized-crime cases, Article 154 permits lawyer consultation to be restricted for up to 24 hours by judicial decision upon the prosecutor’s request.

Crucially, the suspect cannot be questioned during that restricted period.

This is an exception, not the ordinary rule.

Can a Foreign Suspect Speak Privately With Their Lawyer?

Yes.

Confidential lawyer-client communication is a fundamental part of the defence.

Article 154 provides that a suspect or defendant can meet with the defence lawyer without requiring a power of attorney and can communicate in a place where conversations cannot be heard by others.

Communications with the lawyer are also protected from ordinary monitoring.

Before giving a police, prosecutor or judicial statement, a foreign suspect should therefore request an opportunity to speak privately with counsel.

This consultation can be essential for understanding:

• the exact alleged offence;
• possible punishment;
• evidence in the file;
• whether to remain silent;
• which documents should be submitted;
• whether detention may be requested;
• immigration consequences; and
• the next stage of the criminal process.

What If the Foreigner Cannot Afford a Lawyer?

Turkish criminal procedure includes appointed defence mechanisms.

Article 150 provides that where a suspect states that they cannot select a lawyer and requests legal assistance, a defence lawyer may be assigned through the bar system.

In certain cases, representation is mandatory even without a specific request, including children, persons unable to defend themselves due to specified disabilities and investigations concerning offences whose statutory minimum sentence exceeds the threshold in Article 150.

A foreign national should therefore tell the authorities clearly if they want a lawyer.

What If the Police Took a Statement Without a Lawyer?

This does not automatically mean that every such statement completely disappears from the file.

However, Turkish law provides an important evidentiary safeguard.

Article 148/4 states that a statement taken by law enforcement without a defence lawyer present cannot be used as the basis of a judgment unless the suspect or defendant later confirms that statement before a judge or court.

The Court of Cassation continues to apply this rule.

For example, a 2026 decision of the 12th Criminal Chamber emphasized that an uncounselled police statement not later confirmed before a judge or court could not be relied upon as the basis for conviction.

This protection can become particularly important for a foreigner who:

• did not understand Turkish;
• misunderstood the translation;
• signed a prepared statement;
• later disputes what was recorded; or
• gave a police statement without legal advice.

Police Cannot Obtain a Statement Through Torture, Threats or Coercion

A criminal statement must be the product of free will.

Article 148 prohibits methods capable of undermining free will, including:

• ill-treatment;
• torture;
• medication;
• exhaustion;
• deception;
• physical force;
• threats; and
• improper psychological or physical interference.

Unlawful benefits cannot be promised in exchange for a statement.

Statements obtained through prohibited methods cannot be treated as lawful evidence merely because the suspect signed the document.

A foreign national who alleges mistreatment should tell:

• the lawyer;
• prosecutor;
• doctor; and
• judge

as soon as possible.

Is a Medical Examination Required During Police Custody?

Medical examination is an important safeguard in Turkish custody procedure.

Under the Regulation on Apprehension, Police Custody and Taking Statements, where an apprehended person is to be placed in custody or force was used during apprehension, the person’s medical condition must be documented by a physician.

Medical assessment is also required at important stages such as:

• transfer of the detained person;
• extension of custody;
• release; and
• transfer to judicial authorities.

If the person’s health deteriorates or there is concern regarding their medical condition, the detained person must be taken for medical examination and necessary treatment.

A foreigner who has been injured should describe every injury to the doctor.

Do not assume that:

“My lawyer can mention it later.”

Contemporaneous medical documentation may become essential evidence.

Does a Foreign Suspect Have the Right to an Interpreter?

Yes.

A person should not be expected to defend themselves in a criminal case conducted in a language they cannot adequately understand.

Article 202 of the Criminal Procedure Code provides that where a defendant or victim cannot adequately express themselves in Turkish, the essential points concerning the accusation and defence must be translated through an interpreter appointed by the court.

This right also applies during the investigation stage to suspects, victims and witnesses. During the investigation, the interpreter is appointed by the judge or prosecutor.

The interpreter’s cost for a suspect or defendant who does not know Turkish is not treated as an ordinary litigation cost payable by the person; Article 324 provides that these interpretation expenses are borne by the Treasury.

Should a Foreigner Accept an Interview in English If English Is Not Their Strongest Language?

Not necessarily.

The relevant issue is not whether the foreigner knows some English or conversational Turkish.

The question is whether the person can understand:

• the accusation;
• legal terminology;
• detailed questions;
• dates and numbers;
• technical expressions; and
• the consequences of their answers

well enough to participate meaningfully in criminal proceedings.

For example, someone may speak enough Turkish to:

• order food;
• conduct daily business;
• speak with colleagues; or
• communicate socially

but still be unable to understand a criminal allegation involving legal concepts such as:

• intent;
• participation;
• possession;
• fraud;
• knowledge;
• consent;
• threat; or
• benefit.

A suspect should request interpretation in the language in which they can defend themselves accurately.

Never Sign a Statement You Do Not Understand

This is one of the most important practical rules for a foreign national.

At the end of a police, prosecutor or judicial statement, a written record is prepared.

The foreign suspect should confirm:

• what language was used;
• whether an interpreter was present;
• whether every answer is recorded accurately;
• whether something important is missing;
• whether the lawyer’s observations are included; and
• whether the document actually reflects what the person said.

A foreigner should not sign a Turkish document merely because a police officer or translator says:

“It is only procedural.”

If the statement is inaccurate, the problem should be raised immediately.

Does a Foreign National Have the Right to Contact Their Embassy or Consulate?

Yes.

Turkish criminal procedure contains a specific protection for foreign nationals.

Article 95 provides that when a foreign person is apprehended or placed in custody, the situation is notified to the consulate of the country of nationality unless the foreigner objects in writing.

The Regulation on Apprehension, Police Custody and Taking Statements similarly provides for notification to the foreigner’s embassy or consulate where the foreigner does not object in writing.

Consular officials may potentially help with matters such as:

• confirming identity;
• contacting family;
• providing information about local lawyers;
• communicating with authorities;
• monitoring the person’s welfare; or
• providing certain forms of consular assistance.

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

The embassy cannot simply order Turkish police, prosecutors or courts to terminate a Turkish criminal investigation.

Can the Foreigner Inform Their Family?

Yes.

Article 95 also requires that when a suspect is:

• apprehended;
• placed in custody; or
• subject to an extension of custody,

a relative or another person identified by the suspect is informed without delay upon the prosecutor’s instruction.

A foreigner should therefore provide accurate contact information for the person they want notified.

What Happens After the Police Interview?

The next step depends upon the evidence and prosecutor’s assessment.

The prosecutor may:

• release the suspect;
• conduct additional investigative procedures;
• take the suspect’s statement personally;
• request judicial control; or
• request pre-trial detention.

Where detention or judicial control is sought, the foreign suspect is generally taken before the Criminal Judgeship of Peace during the investigation stage.

What Is Pre-Trial Detention — Tutuklama?

Tutuklama is not the same thing as police custody.

Police custody is temporary detention during the initial investigation.

Pre-trial detention is a judicial measure ordered by a judge.

Under Article 100, pre-trial detention may be ordered where there are:

1. concrete evidence showing strong suspicion that the person committed the offence; and
2. a statutory ground for detention.

Possible detention grounds include concrete circumstances indicating that the suspect may:

• flee;
• hide;
• destroy evidence;
• conceal or alter evidence; or
• pressure witnesses, victims or others.

Pre-trial detention must also be proportionate to the seriousness of the case.

Therefore:

Being foreign is not itself a legal ground for imprisonment pending trial.

However, the court may examine factors relevant to flight risk.

For a foreign suspect, this makes evidence of stable connections with Turkey particularly important.

What Evidence Can Reduce an Alleged Flight Risk?

Where the prosecutor requests detention of a foreign suspect, the defence may present evidence such as:

• valid residence permit;
• work permit;
• Turkish employment;
• company ownership;
• Turkish property ownership;
• spouse living in Turkey;
• children attending school in Turkey;
• permanent address;
• previous voluntary appearances before authorities;
• absence of an attempt to leave Turkey;
• return ticket consistent with an ordinary trip;
• cooperation with the investigation; and
• other substantial ties.

These facts do not automatically prevent detention.

However, they may help demonstrate that less restrictive measures can adequately protect the criminal process.

Who Decides Whether a Foreign Suspect Is Detained Pending Trial?

During the investigation, the prosecutor may request detention.

The prosecutor does not issue the judicial detention order.

Article 101 provides that pre-trial detention during the investigation is ordered by the Criminal Judgeship of Peace upon the prosecutor’s request.

The prosecutor’s request must be reasoned and must explain why judicial-control measures would be inadequate.

A detention decision must identify concrete grounds relating to:

• strong suspicion;
• detention grounds;
• proportionality; and
• why judicial control would be insufficient.

Importantly, where detention is requested, the suspect has the right to assistance of a chosen or appointed defence lawyer.

Can a Detention Decision Be Challenged?

Yes.

A pre-trial detention decision can be challenged through the applicable criminal procedure objection mechanism.

Article 101 expressly recognizes a right to object against detention-related decisions.

The defence can argue, depending upon the case, that:

• strong suspicion does not exist;
• evidence is already collected;
• no risk of interference exists;
• there is no realistic flight risk;
• the suspect has substantial Turkish ties;
• the potential sentence does not justify detention;
• detention is disproportionate; or
• judicial control is sufficient.

Applications for release may also be made during the criminal process.

What Is Judicial Control — Adli Kontrol?

Judicial control is a less restrictive alternative to pre-trial detention.

Instead of placing the suspect in prison, the judge may impose obligations designed to secure the criminal proceedings.

Depending upon the case, measures can include restrictions such as:

• prohibition on leaving Turkey;
• regular reporting to authorities;
• financial security;
• restrictions concerning particular activities;
• residence-related obligations; and
• other statutory measures.

For foreign nationals, the most common measure is often a:

travel ban — yurt dışına çıkış yasağı.

The foreign suspect may therefore be released but prevented from leaving Turkey until the restriction is changed or removed.

Does a Travel Ban Mean the Passport Is Cancelled?

Not necessarily.

A judicial prohibition on leaving Turkey is a criminal-procedure measure preventing departure while the order remains in effect.

The person’s passport and nationality remain separate matters.

However, the travel restriction can have major practical consequences for a foreigner who:

• normally lives abroad;
• works internationally;
• needs to travel for business;
• has family outside Turkey; or
• entered Turkey only as a tourist.

The defence may request modification or removal of the judicial-control order where circumstances justify it.

Can Police Search a Foreign Suspect’s Hotel Room, Home or Belongings?

Criminal investigations may involve searches and seizure of evidence.

Searches of:

• a home;
• hotel accommodation;
• workplace;
• vehicle;
• luggage; or
• personal belongings

must comply with Turkish criminal procedure and other applicable legislation.

Whether a judicial order is required and what exceptions apply depends upon the nature and urgency of the search.

Foreign tourists should not assume that staying in a hotel eliminates ordinary privacy and procedural protections.

At the same time, refusal to cooperate physically with a lawful search can create additional problems.

Where there is uncertainty, the foreigner should state that they want their lawyer informed and should avoid signing inaccurate search records.

Can the Police Seize a Foreigner’s Phone?

Potentially, yes.

Mobile phones are frequently important evidence in modern Turkish criminal investigations.

Authorities may seek evidence involving:

• messages;
• call records;
• photographs;
• banking transactions;
• social media;
• location data;
• email;
• cryptocurrency;
• digital documents; or
• communication between suspects.

Seizure and forensic examination of digital material are governed by specific criminal procedure rules and require the applicable legal authorization.

A foreigner whose telephone, laptop or other device is seized should obtain documentation identifying the item taken.

The defence lawyer should later examine:

• the legal basis for seizure;
• scope of the forensic examination;
• chain of custody;
• relevance of extracted material; and
• whether privileged or unrelated material is involved.

What Happens If Illegal Evidence Is Collected?

Turkish criminal procedure follows the principle that criminal responsibility must be established through lawfully obtained evidence.

Coercively obtained statements are expressly prohibited under Article 148.

Questions concerning unlawfully obtained evidence can also arise from:

• unlawful searches;
• unlawful seizures;
• unauthorized communications monitoring;
• procedural violations in digital examination; or
• other investigative measures.

A defence lawyer should therefore review not only what the evidence allegedly proves but how it was obtained.

Does Arrest Mean the Foreigner Is Guilty?

No.

Apprehension, custody and pre-trial detention are procedural measures.

They are not criminal convictions.

The Turkish Constitutional Court emphasizes that the presumption of innocence requires a person accused of an offence to be treated as innocent until guilt is established by a final judgment.

This distinction is particularly important where media reports describe a foreigner as though guilt has already been established.

Terms such as:

• suspect;
• defendant;
• detained person; and
• convicted person

have different legal meanings.

What Happens After the Criminal Investigation?

The prosecutor ultimately evaluates the evidence collected during the investigation.

The prosecutor may conclude that there is insufficient basis for prosecution and issue a decision not to prosecute.

Alternatively, where sufficient suspicion exists, the prosecutor may prepare an indictment — iddianame.

The indictment is submitted to the competent criminal court.

If the court accepts the indictment, the case moves from the investigation stage — soruşturma to the prosecution/trial stage — kovuşturma.

The foreigner then becomes a defendant before the criminal court.

Which Criminal Court Will Hear the Case?

The competent court depends on the alleged offence.

Proceedings may be heard before courts including:

• Criminal Court of First Instance — Asliye Ceza Mahkemesi;
• High Criminal Court — Ağır Ceza Mahkemesi; or
• another specialized criminal court where legislation so provides.

Serious offences carrying substantial imprisonment are generally heard before the High Criminal Court.

A foreign national should not attempt to determine the seriousness of the case simply from the name given by police.

The exact Turkish Criminal Code article alleged is critical.

Does the Foreign Defendant Need an Interpreter at Trial?

Yes, where the defendant cannot adequately understand or express themselves in Turkish.

Article 202 requires interpretation of essential aspects of the accusation and defence through a court-appointed interpreter.

Interpretation should enable meaningful participation.

The defendant should be able to understand:

• the indictment;
• witness evidence;
• questions from the court;
• prosecutor’s submissions;
• expert evidence where relevant;
• defence submissions; and
• the judgment.

Where a translation appears inaccurate, the lawyer should raise the issue immediately.

Can a Foreigner Be Tried Without Being Physically in Turkey?

This depends heavily upon the offence, procedural stage and whether the court requires the defendant’s presence.

Some proceedings and procedural steps may potentially continue through legal representation.

In other cases:

• personal defence;
• judicial questioning;
• arrest warrant;
• testimony; or
• other procedural requirements

may make the person’s presence necessary.

A foreigner who leaves Turkey while a criminal investigation is unresolved should not assume the file disappears.

Possible consequences can include:

• summons;
• arrest warrant;
• judicial-control violations;
• border alerts; or
• future difficulties entering Turkey.

Can a Criminal Case Lead to Deportation?

Potentially, yes.

Criminal proceedings and immigration proceedings are separate, but they can interact.

Under Law No. 6458 on Foreigners and International Protection, certain criminal, public-order and security circumstances can lead to:

• residence permit cancellation;
• deportation;
• administrative immigration detention;
• restriction codes; or
• entry bans.

However, the existence of a police investigation does not mean every foreign suspect is automatically deported.

The immigration measure must have its own legal basis.

Therefore, where a foreign national is arrested, the legal strategy should consider both:

the criminal file

and

the immigration file.

What If the Criminal Case Ends in Acquittal?

An acquittal can be extremely important, particularly where an immigration restriction was based on the same criminal allegation.

However, criminal and administrative immigration procedures are legally separate.

The foreign national may still need to request:

• cancellation of an entry ban;
• removal of a restriction code;
• reconsideration of a residence decision; or
• annulment of another administrative measure.

The acquittal judgment becomes important evidence in that separate procedure.

Arrest at Istanbul Airport or Another Turkish Border Crossing

Foreign nationals sometimes discover a criminal investigation only when they attempt to:

• enter Turkey;
• leave Turkey; or
• transit through an airport.

A previous criminal file may contain:

• an outstanding arrest warrant;
• order to take a statement;
• judicial-control measure;
• conviction-related enforcement record; or
• another judicial alert.

The person can therefore be apprehended during passport control.

In such circumstances, the first questions should be:

1. Which authority issued the record?
2. Which court or prosecutor’s office is involved?
3. What is the file number?
4. Is the person wanted only for a statement or under an arrest warrant?
5. Is there also an immigration restriction?

The existence of a border alert does not tell the entire legal story.

Should the Foreigner Contact Their Embassy First or a Turkish Lawyer First?

Both can be useful, but they perform different functions.

The embassy or consulate provides consular assistance.

A Turkish criminal defence lawyer provides legal defence inside the Turkish criminal justice system.

The lawyer can:

• meet the detained person;
• examine available criminal records;
• attend the police statement;
• attend prosecutor questioning;
• attend the Criminal Judgeship of Peace hearing;
• oppose detention;
• request judicial control instead;
• challenge detention;
• collect exculpatory evidence;
• communicate with family; and
• follow the criminal file.

If the person faces an immediate police interview or detention hearing, criminal defence assistance is especially time-sensitive.

What Should a Foreign National Do Immediately After Arrest in Turkey?

A foreign national who is apprehended should, where possible:

1. Remain calm and do not physically resist lawful police action.
2. Ask why they are being apprehended.
3. Ask for the alleged offence or file information.
4. Clearly request a lawyer.
5. Request an interpreter if Turkish is not fully understood.
6. Consider exercising the right to remain silent until legal advice is obtained.
7. Request notification of a family member or trusted person.
8. Request consular notification where desired.
9. Do not sign documents that are not understood.
10. Tell the doctor about any injury or medical condition.
11. Inform the lawyer of medications or urgent medical needs.
12. Preserve copies or details of documents served by authorities.

The foreigner should also avoid trying to explain a complicated allegation informally to multiple police officers before understanding the file.

Common Mistakes Foreigners Make After Being Arrested in Turkey

Giving an Immediate Detailed Statement Without a Lawyer

The suspect may believe that giving a long explanation will produce immediate release.

Sometimes it does.

Sometimes it unintentionally supplies missing evidence to the prosecution.

Legal strategy should come first.

Signing a Turkish Statement Without Reading the Translation

Never treat the final interview record as a formality.

It may later be examined by:

• the prosecutor;
• detention judge;
• trial court;
• appeal court; and
• immigration authorities.

Using an Informal Friend as the Only Translator

Criminal proceedings require reliable interpretation.

A friend can assist with communication but should not automatically replace the procedural interpreter required by the criminal justice system.

Believing the Embassy Is the Defence Lawyer

Consular officials cannot conduct the Turkish criminal defence.

Deleting Messages or Digital Evidence

Trying to erase evidence after learning of an investigation can make the legal situation worse and may be relied upon as evidence of interference with the investigation.

The lawyer should determine what material should be preserved and submitted.

Contacting the Complainant or Witnesses

A suspect may think:

“I will explain everything directly and the complaint will disappear.”

This can create allegations of:

• pressure;
• threats;
• evidence interference; or
• witness influence.

Such conduct may also strengthen an argument for pre-trial detention under Article 100.

Leaving Turkey in Violation of a Travel Ban

A judicial travel prohibition must be treated seriously.

Attempting to circumvent the order can create additional legal consequences.

Assuming Release Means the Case Is Finished

A suspect may be released after the police interview while the prosecutor continues the investigation for months.

Release from custody does not mean the file is closed.

Frequently Asked Questions

Can Turkish police arrest a foreign tourist?

Yes. Foreign tourists are subject to Turkish criminal law for offences within Turkish jurisdiction.

Does a foreigner have the same right to a lawyer?

Yes. Foreign nationality does not eliminate the right to legal assistance.

Can I remain silent?

Yes. Article 147 requires suspects to be informed of the right not to make a statement about the accusation.

Must I provide my identity?

Yes. The suspect must answer identity-related questions accurately, although this is different from providing a substantive statement concerning the alleged offence.

Can police question me without a lawyer?

The legal analysis depends upon the circumstances and whether mandatory defence applies, but an uncounselled police statement cannot form the basis of a judgment unless later confirmed before a judge or court under Article 148/4.

Can I ask for a free lawyer?

A lawyer can be appointed through the bar system where the conditions of Article 150 apply. Mandatory appointment also applies to certain categories of suspects.

Can I speak privately with my lawyer?

Yes. Article 154 protects confidential lawyer-client consultation.

Can police prevent me from seeing my lawyer?

Only limited statutory exceptions exist. In specified serious offences, access can be restricted for up to 24 hours by judicial decision on the prosecutor’s request, but no statement can be taken during that restriction period.

Do I have the right to an interpreter?

Yes, if you cannot adequately understand or express yourself in Turkish.

Do I have to pay the criminal interpreter?

The cost of an interpreter appointed for a suspect or defendant who does not know Turkish is borne by the State Treasury rather than treated as an ordinary litigation expense.

Will my embassy be informed?

Where an apprehended or detained person is foreign, the consulate is notified unless the foreigner objects in writing.

Can my family be informed?

Yes. Turkish procedure provides for notification of a relative or another person identified by the suspect.

How long can ordinary police custody last?

The ordinary maximum is 24 hours, excluding a transportation period of up to 12 hours. Different extension mechanisms apply in collective and specified serious cases.

Can I challenge police custody?

Yes. Article 91 provides for an application to the Criminal Judgeship of Peace challenging apprehension, custody or extension.

Is police custody the same as imprisonment pending trial?

No.

Gözaltı is temporary police custody.

Tutuklama is pre-trial detention ordered by a judge.

Can the prosecutor put me in prison?

The prosecutor may request pre-trial detention, but during the investigation the judicial detention decision is made by the Criminal Judgeship of Peace.

What is required for pre-trial detention?

Article 100 requires concrete evidence showing strong criminal suspicion together with a detention ground, and detention must be proportionate.

Can a foreigner be released under judicial control?

Yes. Judicial control can be used as an alternative to pre-trial detention.

Can the judge prohibit me from leaving Turkey?

Yes. A foreign-travel prohibition can be imposed as a judicial-control measure.

Can my mobile phone be seized?

Potentially, where the applicable criminal procedure conditions for seizure and digital examination are satisfied.

Can I be deported because I was arrested?

An arrest does not automatically produce deportation. However, criminal proceedings can trigger separate immigration measures in qualifying circumstances.

Does an acquittal automatically remove an entry ban?

Not necessarily. The immigration measure may require a separate administrative application or lawsuit.

Conclusion

A foreign national who is arrested or detained in Turkey has substantial procedural rights under Turkish law.

Foreign citizenship does not allow the police, prosecutor or court to disregard the safeguards contained in Criminal Procedure Code No. 5271.

From the moment of apprehension, the foreign suspect should understand the difference between:

• yakalama — apprehension;
• gözaltı — police custody;
• tutuklama — judicial pre-trial detention; and
• adli kontrol — judicial control.

Each is a separate legal measure with different conditions and remedies.

The first hours are especially important.

Under Article 147, the suspect must be informed of the accusation, the right to legal assistance and the right to remain silent.

A foreign suspect who does not understand Turkish is entitled to interpretation under Article 202, including during the investigation stage.

The suspect is also entitled to consult privately with a defence lawyer, and Article 154 protects the confidentiality of that consultation.

These rights should be used in practice rather than treated as technical formalities.

A foreign national should not sign a statement that they do not fully understand.

They should not assume that conversational Turkish is sufficient for understanding detailed criminal-law terminology.

They should not give a long substantive explanation merely because they believe immediate cooperation guarantees release.

And they should not assume that an embassy can replace a Turkish criminal defence lawyer.

Foreign nationals have an additional protection regarding consular communication.

Where a foreign person is apprehended or placed in custody, Article 95 requires notification to the person’s consulate unless the foreigner objects in writing.

Police custody is also subject to strict time limits.

The ordinary Article 91 period is 24 hours from apprehension, excluding the permitted transportation period of up to 12 hours, although special extension regimes exist for collective and specified serious offences.

If the suspect is not released, the person must ultimately be brought before the judicial authority.

At that point the prosecutor may request:

• detention;
• judicial control; or
• another measure.

A prosecutor’s request for detention does not itself place the foreigner in pre-trial prison.

The Criminal Judgeship of Peace must make the judicial decision.

Articles 100 and 101 require strong suspicion supported by concrete evidence, a legally recognized detention reason, proportionality and an assessment of whether judicial control would be sufficient.

For foreign suspects, arguments concerning flight risk frequently become important.

Evidence of:

• a Turkish residence permit;
• Turkish property;
• employment;
• company ownership;
• spouse;
• children;
• permanent address;
• previous lawful residence; and
• voluntary cooperation

may therefore become relevant when arguing that detention is unnecessary and judicial control is sufficient.

The foreigner should also understand that a criminal investigation can create a second legal problem: immigration consequences.

A criminal allegation may, depending upon its nature, result in separate proceedings concerning:

• residence status;
• work permit;
• deportation;
• entry ban; or
• restriction codes.

These are administrative immigration measures and must be distinguished from the criminal prosecution itself.

Accordingly, an effective defence strategy for a foreign national may require simultaneous examination of:

the criminal investigation and the immigration record.

The most important practical approach after an arrest is therefore simple:

request a lawyer, request an interpreter where necessary, understand the accusation, preserve the right to remain silent until an informed defence strategy is determined, ensure family and consular notification, document medical issues and carefully review every document before signing.

In criminal proceedings, statements made during the first hours can remain in the file throughout the investigation, trial and appeal process.

For a foreign suspect who must simultaneously overcome language barriers, unfamiliar procedures and potential immigration consequences, obtaining competent Turkish criminal defence assistance at the earliest stage can therefore be particularly important.
