What should family members do after receiving the notice of criminal detention?

Legal analysis: after receiving the notice of criminal detention, family members can first learn the facts of the suspected crime from the public security organ or procuratorate handling the case. Then ask the case-handling organ about the place of detention. If a detention notice has not been received for several days, the family members can contact the local police station directly to find out whether there is a detention notice, so as to know the place and reason of the prisoner's detention. If family members know where their relatives are detained or arrested, they can hire lawyers to meet at the detention center in time to safeguard the legitimate rights and interests of the parties.

Legal basis: Article 34 of the Criminal Procedure Law of People's Republic of China (PRC). A criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or takes compulsory measures. During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time. When interrogating a criminal suspect for the first time or taking compulsory measures against him, the investigation organ shall inform him that he has the right to entrust a defender. The people's procuratorate shall, within three days from the date of receiving the case materials transferred for examination and prosecution, inform the criminal suspect that he has the right to entrust a defender. The people's court shall, within three days from the date of accepting the case, inform the defendant of the right to entrust a defender. If a criminal suspect or defendant requests to entrust a defender while in custody, the people's court, the people's procuratorate and the public security organ shall promptly convey it. If a criminal suspect or defendant is in custody, his guardian or near relative may also entrust a defender. After accepting the entrustment of a criminal suspect or defendant, the defender shall promptly inform the case-handling organ.
