To determine which detention center the prisoner is in, you can go to the place where the detainee is located or entrust a lawyer to inquire with the public security organ. The detention center holds people who have been punished by administrative detention, so the detention center is the state administrative detention organ. The object of detention in the detention center is the person detained by the public security and the person who is decided by the court to judicial custody. After detention, the public security organ will inform the family members in time, so that they can know which detention center they are in by consulting their families.
Legal objectivity:
Article 85 of the Criminal Procedure Law of People's Republic of China (PRC), when a public security organ detains a person, it must produce a detention permit. After detention, the detained person shall be immediately sent to the detention center for custody, and shall not exceed twenty-four hours. Unless it is impossible to notify or the notification of suspected crimes endangering national security or terrorist activities may hinder the investigation, the family members of the detained person shall be notified within 24 hours after detention. After the circumstances that hinder the investigation disappear, the family members of the detained person shall be notified immediately.
