Legal analysis: the document that the public security organ notifies the family members after detaining the criminal suspect is called the detention notice, which is a legal document made by the public security organ. The public security organ will indicate the name of the suspect, the alleged crime, the legal basis of criminal detention, the detention time and the detention center on this material, affix the seal of the public security organ, and send it by registered mail of China Post. What needs to be reminded here is that the receiving address of the detention notice issued by the case-handling organ is often provided by the suspect. If the address provided by the suspect is wrong or the family member is not at the receiving address, it may not be accepted. In addition, detention notices are almost always sent by registered mail, which may not be received due to outdated methods. This happens from time to time. Therefore, if the family suddenly loses contact for a long time, they should report to the local police station and apply for an inquiry. If you are really in criminal detention, you can find out the time and reason of detention, provide legal help to your lawyer, and send clothes and living expenses.
Legal basis: Article 91 of the Criminal Procedure Law of People's Republic of China (PRC). If the public security organ deems it necessary to arrest the detained person, it shall submit it to the people's procuratorate for examination and approval within three days after detention. Under special circumstances, the approval time can be extended by one to four days. For major suspects who commit crimes on the run, commit crimes many times or commit crimes in collusion, the time for submitting for examination and approval may be extended to 30 days. The people's procuratorate shall, within seven days after receiving the approval letter from the public security organ, make a decision on whether to approve or disapprove the arrest. If the people's procuratorate does not approve the arrest, the public security organ shall immediately release it after receiving the notice and promptly notify the people's procuratorate to execute it. Those who need to continue the investigation and meet the conditions of obtaining a guarantor pending trial or residential surveillance shall be granted a guarantor pending trial or residential surveillance according to law.
