As a prisoner, when his personal belongings are temporarily detained, the police should also issue a seizure document and a seizure list. If it is found that it has nothing to do with the case, it shall be returned to the parties or their families within 3 days, and the corresponding procedures shall be performed. If it is a criminal tool, it should be confiscated according to law. According to what you said, the prisoner must have decided that the case has come into effect and been executed. At this time, the handling of the property involved should have been completed. Until now, there are relatively few cases in which the mobile phone involved has not been handled. In fact, if the family members of the prisoners have the seizure notice or list issued by the police, they can ask the police to return it at any time.
