Whether or not the detention center will notify the family members in advance depends on the specific situation. According to relevant laws and regulations, before a detainee is released from the detention center, the department in charge of the detainee's file will notify the detainee's family in the form of ** or a letter. In the case of criminal detention, the family is usually notified within a certain period of time after the detention. However, if it is a case of other circumstances, such as bail, release on bail, etc., the family may be notified in advance.
When a person is released from a detention center, the detention center will require the released person to sign relevant documents, such as a release certificate, to prove that he or she has been released. At the same time, the detention center will also provide some necessary services, such as helping the released person go through the formalities for leaving the detention center and providing transportation. If the released person has no family members or the family members are unable to come to pick them up, the detention center will also provide some assistance, such as arranging accommodation and providing meals.
In general, detention centers will adopt different notification methods and measures according to the specific circumstances when releasing detainees, so as to ensure that the released persons can return to society safely and smoothly. At the same time, released persons and their families should also be aware of the relevant legal provisions and procedures so as to better protect their legitimate rights and interests.
