According to the provisions of Article 9 of the Regulations on Detention Centers, criminals detained in detention centers must pursue and temporarily detain criminals with arrest warrants held by dispatched agencies, criminal detention certificates issued by public security organs and state security organs at or above the county level, or certification documents issued by public security organs, state security organs, prisons, reform-through-labor institutions, people's courts and people's procuratorates at or above the county level. If there is no such certificate, or the record of the certificate is inconsistent with the actual situation, it will not be taken into custody.
At the same time, according to the provisions of Article 11 of the Measures for the Implementation of the Detention Center Regulations, when the case-handling organ needs to transfer the detainees to another organ for jurisdiction, it shall fill out the Transfer Certificate and affix the official seal to transfer them with the case. The receiving organ shall affix the official seal on the exchange certificate, indicate the undertaking time, and send it to the detention center in time. The detention center shall go through the formalities of prisoner exchange with the exchange certificate, and immediately issue a receipt and return it to the transfer organ.
