When the police station summons for public security, it should inform the suspects of the reasons and basis for summoning, and suggest actively cooperating with the investigation by the public security organs. Articl《刑事诉讼法》 stipulates that a criminal suspect who does not need to be arrested or detained may be summoned to a designated place in the city or county where the criminal suspect is located or to his residence for interrogation, but the documents of the procuratorate or the public security organ shall be produced.
