Summoning is a way for investigators of people's procuratorates or public security organs to question criminal suspects. The Provisions on the Procedures of Public Security Organs for Handling Criminal Cases stipulates that the public security organs can summon a criminal suspect to a designated place with the approval of the person in charge of the case-handling department of the city, county or trial place where the criminal suspect is located.

There are two ways to summon suspects after filing a case:

1. For criminal suspects who do not need to be arrested or detained, they can be directly summoned to the designated place or residence or unit for interrogation, and they can produce the certificates of the people's procuratorate or the public security organ;

2, for illegal suspects need to be summoned for investigation, with the approval of the person in charge of the police station or the public security organ at or above the county level, use a summons card to summon.

According to the law of our country, when summoning a criminal suspect, he should show his summons card and the investigator's work permit, and order him to sign the summons card and press his fingerprint. For the criminal suspect found at the scene, the investigator can show his work permit and summon him orally, and inform the summoned person of the reasons and basis. The duration of summons shall not exceed 12 hours, and criminal suspects shall not be detained in disguised form by continuous summons. Summoning a criminal suspect shall ensure the suspect's diet and necessary rest time.
