The police verbally summoned him not to say why.

If the police verbally summon without giving reasons, citizens have the right to refuse the off-duty summons, and they can complain and report the illegal acts to the competent leader, the discipline inspection and supervision department or the public security organ at the next higher level. The law authorizes public security organs to exercise administrative powers such as summoning, oral summoning and compulsory summoning in accordance with relevant laws.

However, in the process of exercising this right, the public security organ shall inform the summoned person of the reasons and basis. If the public security organ refuses to inform the summoned person of the reasons and basis for summoning, its behavior does not belong to performing the duties authorized by law, and citizens have the right to refuse the non-duty behavior of the public security organ.

Summoning is a measure for judicial organs to inform litigants to appear in court at a specified time and place. According to Article 92 of China's Criminal Procedure Law, "A criminal suspect who does not need to be arrested or detained may be summoned to a designated place or residence or unit for interrogation, but the certificate of the people's procuratorate or the public security organ shall be produced." The purpose of summoning is to ensure that criminal proceedings are carried out in a planned way and cases are handled in time, and legal litigation documents-summonses must be used for summoning. If it is necessary to summon an illegal suspect for investigation, with the approval of the person in charge of the case handling department of the public security police station or the public security organ at or above the county level, a summons card shall be used for summons.

After showing their work certificates, the people's police can verbally summon the illegal suspects found on the spot, and indicate the process, time and departure time of the illegal suspects in the interrogation record. The public security organ shall inform the summoned person of the reasons and basis for summoning. For those who refuse to accept or evade the summons without justifiable reasons, and other offenders who can be summoned according to law, they can be summoned by force. When forced to summon, you can use binding police equipment such as handcuffs and police ropes according to law. When the public security organ summons an illegal suspect, if his family members are present, he shall verbally inform his family members of the reason and place for summoning on the spot, and indicate it in the inquiry record.

Article 82 of People's Republic of China (PRC) Public Security Administration Punishment Law

If it is necessary to summon a person who violates the administration of public security for investigation, he shall be summoned with a summons card with the approval of the person in charge of the case-handling department of the public security organ. The people's police may summon an offender found on the spot who violates the administration of public security orally after producing his work certificate, but it shall be indicated in the inquiry record. The public security organ shall inform the summoned person of the reasons and basis for summoning. A person who refuses to accept a summons or evades it without justifiable reasons may be summoned by force.
