According to Article 62 of the Criminal Procedure Law of People's Republic of China (PRC), criminal suspects and defendants may be detained or placed under residential surveillance during investigation and trial. If the police station decides to send the suspect to the detention center, it needs the approval of the procuratorate and review it within the specified time. In this process, criminal suspects and defendants cannot move freely, nor can they escape on the grounds of looking for someone. Therefore, the criminal case police station said that you can't find anyone hiding in the detention center 10 days.
If a criminal suspect or defendant wants to avoid being detained or under residential surveillance, it needs to be solved through legal channels, such as hiring a lawyer to defend or applying for bail pending trial.
