Some of my friends smashed the windows of other people's shops with iron bars because they spent some holidays with others. They were detained in criminal detention on the 27th of last month and have not been released yet. Excuse me. ... Criminal detention will not exceed 15 days. However, if the police have investigated all the incidents and think it is necessary to prosecute, then your friend is not in a state of "detention" but in a state of "arrest". Then the procuratorate will review the judgment of the prosecution court. It depends on the seriousness of the matter before knowing when it will come out.
