When it comes to the procedure of collecting information for conducting a criminal investigation and, on the other hand, at the same time providing evidence within the criminal procedure, it is standardized through the provisions of the legal and sub-legal level. Certain documents play an exceptional role in this procedure as well as in the entire criminal procedure, and among them it is possible to highlight the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights as well as the European Convention for the Protection of Fundamental Rights and Fundamental Freedoms. Through the Law on Police Duties and Powers, the collection of information from citizens is standardized as a special area. Based on the rules, it is possible for police officers to call citizens with the basic aim of collecting information. As for the coercive method, in that case the suspect who accordingly did not respond to the sent summons can be brought. The above-mentioned item can be done in situations where the aforementioned person was warned, that is, when the suspect was forcibly brought, and refuses to give any notification and cannot be summoned again for the same reason. The suspect who was forcibly brought must be informed of the specific reasons for summoning, i.e. the basic suspicions against him. At the same time, the suspect must be familiar with all the issues related to the rights he has.
