A summons from the Criminal Police Team does not necessarily mean a case has been filed.

Summons are divided into two types: criminal summons and public security summons. Even without filing a case, the public security organs have the power to summon criminal suspects to designated locations for questioning, but the relevant departments must issue supporting documents when summoning. A summons is a measure taken by judicial organs to notify litigants to appear at a designated time and place.

For illegal suspects found at the scene, the people's police can verbally summon them after showing their work IDs, and indicate in the inquiry transcript how the illegal suspect arrived at the case, the time of arrival and the time of departure. The public security organ shall inform the person being summoned of the reason and basis for the summons. Those who violate the public security management who refuse to accept the summons or evade the summons without justifiable reasons, as well as other illegal actors who can be compulsorily summoned according to the law, may be compulsorily summoned. When imposing a compulsory summons, restraint police equipment such as handcuffs and police ropes may be used in accordance with the law.

In summary, for criminal suspects who do not need to be detained, the public security organs can summon the suspect to a designated location for interrogation.

Legal basis:

"Procedural Regulations of Public Security Organs in Handling Criminal Cases"

Article 199

Summoning of Criminal Suspects When arresting someone, they shall produce the summons card and the people's police card of the investigating personnel, and order them to sign and fingerprint the summons card.

After the criminal suspect arrives at the case, he shall fill in the time of arrival on the summons. When the summons ends, the person shall fill in the summons end time on the summons certificate. If the criminal suspect refuses to fill in the form, the investigators shall indicate it on the summons.
