Legal analysis: You can call the police. If the police believe that criminal responsibility needs to be pursued, they will open a case for investigation. If they do not pursue criminal responsibility, they will notify the reporter of the reason for not opening the case. The law stipulates that after the public security organ accepts a case and upon review, considers that there are criminal facts that require criminal liability and that it falls within its own jurisdiction, the case shall be filed with the approval of the person in charge of the public security organ at or above the county level.
