If you are arrested by the police, you will inform your family.

The police usually notify the family members within 24 hours after the arrest. According to the law, after detention, the detained person should be sent to the detention center for custody immediately, and no later than 24 hours. And within 24 hours, a notice of detention will be issued and delivered to the families or units of the detainees.

First, for several situations in which you don't tell your family after detention?

(1) The suspect in the same case may escape, conceal, destroy or forge evidence;

(two) do not speak the real name and address, the identity is unknown;

(three) other obstacles to the investigation or unable to notify.

After the above situation is eliminated, the family members of the arrested person or their units shall be notified immediately.

If there is no notice within twenty-four hours, the reasons shall be stated in the notice of arrest.

Second, detained relatives should do several things:

1, confirm the real situation.

According to Article 125 of China's "Procedures for Handling Criminal Cases by Public Security Organs", after detaining a criminal suspect, the detainee's family members or their units shall be informed of the reasons and places of detention within 24 hours, except those that hinder the investigation or cannot be notified. If you hear that your family has been arrested and have not received the notice of criminal detention, you can directly ask the case-handling organ for information.

2. Confirm the place where their relatives are being held.

The place of detention can be determined by the detention center designated by the criminal detention notice; If you don't receive the Notice of Criminal Detention in time, you can directly submit it to the investigation organ handling the case.

3. If the family gets the notice of criminal detention, it means that the investigation organ has some evidence, and the family may have been suspected of committing a crime.

Three, criminal detention must meet two conditions at the same time:

1. The object of detention is a flagrante delicto or a major suspect. An active criminal refers to a person who is committing a crime, and a major suspect refers to a person who has evidence to prove that he is suspected of a major crime.

It has a legal emergency. Regarding what is an emergency, Article 80 and Article 163 of the Criminal Procedure Law have different provisions on detention by public security organs and detention by people's procuratorates.

Legal basis:

Criminal Procedure Law of the People's Republic of China

Article 85

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.
