3. Arrest the suspect: Once the identity of the suspect is confirmed, the police will take necessary actions, including issuing arrest warrants and launching arrests.
4. Trial: After the suspect is arrested, he will be handed over to judicial organs for trial. According to the value and circumstances of theft, you may face corresponding criminal punishment.
