The public security bureau asked me for my son's phone number. Can I not give it?

Public security organs will not summon the parties in their own names, so under normal circumstances, they will not notify their families by mobile phones. When the public security organs communicate with the families of criminal suspects, they usually use the telephone of the unit or go to the door directly to find them. The public security bureau will not inform you by sending text messages or making personal calls. If you receive some phone calls or text messages with mobile phone numbers or ordinary phone numbers, they are generally fake. For the illegal acts found on the spot, the police station of the police station can verbally summon them. For illegal acts found off-site, the police station of the police station shall use the summons card, and generally do not use the telephone to inform. The extended information police can arrest people in several ways:

1. If summoning is applicable, the police station will make a notice of summoning family members.

2, administrative detention, administrative detention notice will be made to inform the family.

3, criminal detention and extended criminal detention, criminal detention notice will be made to inform the family.

4. In case of arrest, make an arrest notice and notify the family members.

5. If informing the family members will affect the detection of the case, it is not necessary to inform the family members (usually in special circumstances such as gang crimes). Baidu Encyclopedia-People's Republic of China (PRC) and Public Security Administration Punishment Law
