What is police detention?
Police detention, often referred to as 48-hour detention, is a short-term deprivation of liberty carried out by the Police or another authorised authority when there are legal grounds to suspect that a person has committed a criminal offence and immediate action is necessary. In Polish criminal procedure, it is not the same as pre-trial detention ordered by a court. Police detention is an urgent procedural measure used at the early stage of a case, before a court decides whether further deprivation of liberty is justified.
The 48-hour time limit is significant because, under Article 41(3) of the Constitution of the Republic of Poland and Article 248 of the Polish Code of Criminal Procedure, a detained person must be released unless they are placed at the court’s disposal within 48 hours together with a request to apply pre-trial detention. If the court does not issue an order for pre-trial detention within 24 hours from the moment the detained person is placed at its disposal, the person must also be released. These limits mean that police detention may lead to court-ordered pre-trial detention, but it cannot be prolonged by the Police at their discretion.
The purpose of police detention is to secure the proper course of proceedings, prevent escape, stop the destruction of evidence, or enable urgent procedural acts such as questioning, identification, searches, or presentation of charges. Detention should be based on statutory grounds and must be proportionate to the circumstances of the case. The mere fact that a person is suspected of an offence does not automatically justify detention.
What does police detention involve?
Police detention usually begins with the physical apprehension of a person and taking them to a police station or another authorised facility. The detained person should be informed of the reasons for detention and of their rights. These rights include, in particular, the right to contact a lawyer, the right to make a statement or refuse to make a statement, the right to notify a close person, employer, school or university, and, in the case of foreign nationals, the right to contact a consular authority. If the detained person does not speak Polish sufficiently, interpretation should be provided.
A protocol of detention should be prepared. It should record the time, place, reasons and circumstances of detention, as well as information on the rights given to the detained person. The exact time is important because statutory time limits are calculated from the moment of actual deprivation of liberty, not from the moment of arrival at the police station.
During detention, the authorities may carry out urgent procedural steps. Depending on the case, this may include questioning the detained person, questioning witnesses, securing digital devices, carrying out a search, presenting charges, or preparing a motion for pre-trial detention. In practice, the first hours after detention are often decisive for the further direction of the case.
A detained person may file a complaint against detention to the court. The court examines whether the detention was lawful, justified and properly executed. This review may be important not only for the immediate situation of the detained person, but also for later assessment of the legality of evidence-gathering actions and potential claims relating to unlawful deprivation of liberty.
When is legal assistance needed in police detention?
Legal assistance is particularly important when a person is detained on suspicion of a criminal offence, economic crime, drug-related offence, violent offence, fraud, forgery, theft, cybercrime, or an offence connected with business activity. It is also relevant where the detained person is a foreign national, does not understand Polish procedure, or faces possible extradition, removal proceedings or other immigration consequences.
For individuals, police detention may involve stress, limited access to information and pressure to provide explanations quickly. For entrepreneurs and managers, detention may also affect business continuity, access to company documents, communication with employees, and reputational risk. In cases involving searches, seizure of data carriers or financial documentation, early legal assessment can help protect procedural rights and business interests.
A prompt consultation with a lawyer may help avoid procedural mistakes, ill-considered statements, missed deadlines, disputes concerning the legality of detention, or decisions that increase the risk of criminal liability or financial loss. Legal support at this stage may include contacting the detained person, participating in questioning, verifying whether the time limits are observed, assessing the grounds for detention, and preparing arguments against a motion for pre-trial detention.
Support of a law firm in matters involving police detention
Support of a law firm in matters involving police detention may include in particular:
- urgent legal consultation for the detained person or their family,
- contact with the Police, prosecutor’s office or court,
- participation of a defence lawyer in questioning and other procedural acts,
- verification of the legality, grounds and duration of detention,
- preparation of a complaint against detention,
- defence against a motion for pre-trial detention,
- assistance in cases involving searches, seizure of documents or electronic devices,
- support for foreign nationals, including consular contact and interpretation issues,
- advice for companies affected by the detention of employees, managers or board members.
Police detention is a time-sensitive situation. The legal assessment should focus on both immediate release-related issues and the broader defence strategy in the criminal proceedings.
