How do network police catch criminals?

This is mainly through an online control platform, which is mainly connected with all hotels, hotels and other places in the country to achieve comprehensive control.

For example, in a murder case, police technicians extract fingerprints to determine the suspect in the fingerprint database, then the network police will input the identity information of the suspect on the centralized control platform, and then the monitoring will be completed. Once the suspect escapes to a certain place, wants to find a hotel to stay, or wants to go to an Internet cafe to surf the Internet, then when registering his ID card, once the waiter enters his ID card into the computer, the alarm of the network police will sound, and the suspect's position can be locked immediately, so as to arrest him.

Therefore, the police in the police station often check whether the ID card registration system in Internet cafes and hotels is implemented, just to play a role at a critical moment. Think about it, if the registration system in these places is not implemented, even if there are suspects coming to live, there is no way to arrest them without registering their ID cards.
