Legal analysis: Generally, public security organs will not send short messages when filing a case, but will take corresponding measures according to the handling procedures. Article 168 When accepting a case, a public security organ shall make a registration form for accepting the case and issue a receipt.

Legal basis: Article 19 of the Criminal Procedure Law of People's Republic of China (PRC), except as otherwise provided by law, criminal cases shall be investigated by public security organs. Crimes such as illegal detention, extorting confessions by torture, and illegal search. When the people's procuratorate conducts legal supervision over litigation activities, it finds that judicial personnel use their powers to infringe upon citizens' rights and damage judicial justice, and may file a case for investigation. If a major criminal case of a functionary of a state organ under the jurisdiction of a public security organ needs to be directly accepted by a people's procuratorate, it may be placed on file for investigation upon the decision of a people's procuratorate at or above the provincial level. Cases of private prosecution are directly accepted by the people's courts.
