Yes, it is possible. The police officer is authorised to order the person, if necessary for performance of the duties according to the Police Corps Law, to prove his/her identity by an ID card (Section 18 of the Police Corps Law). At each stage of the criminal proceedings, the competent criminal authority shall verify the identity of the person involved prior to performing the given measure. In the event the ordered person refuses to prove his/her identity or is unable to reasonably prove his/her identity, such person may be taken to a police department in order to prove his/her identity.
Identity of the person may be verified pursuant to Section 155 (5) of the Criminal Procedure Code, when the evidence requires that it is necessary to establish the identity of the person who remained at the crime scene. The person concerned is obligated to submit to the acts necessary for such findings, including the collection of finger prints. Section 126 of the CPC also regulates the identification of a person by recognition (either in person, or by photographs, or with using of technical means).
