How long will it take to inform the family members when they are taken away by the police?

24 hours later. 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. Second, what should I do if my relatives and friends are arrested and detained? First of all, don't panic when you hear or know that your relatives and friends are under criminal detention. First, do everything possible to find out what charges are suspected, which public security and procuratorial organs arrested them and held them in that detention center. As for how to know the charges and the place of detention, you can go to the investigation organ and ask the host police officer.

Secondly, if you know the basic situation or can't understand the relevant situation, hire a lawyer to intervene as soon as possible. Lawyers can help you understand the accused charges, go to the detention center to meet the detained relatives and friends, ask for confessions, and get to know the case as soon as possible. It is suggested that we should not sign the whole criminal agency contract with lawyers at this time, but only sign the lawyer meeting contract, so that after learning more, we can have a broader space to choose lawyers according to our own situation. Of course, you can also choose legal aid or hire your own lawyer according to your own conditions. Thirdly, interview a lawyer after the meeting, and the lawyer will help you analyze whether the charges are established according to the case and his own practical experience, and what punishment will be imposed if the charges are established. After patiently listening to the lawyer's analysis of crime, he will put forward his own ideas. At this time, he can generally judge whether the lawyer is professional, whether he can help himself, whether he can let his relatives and friends be released in advance, or get a bail pending trial, and be sentenced to a shorter sentence, and then decide whether to sign a criminal agency contract or hire someone more capable.
