This case has been dealt with. If the party concerned is the perpetrator, the public security organ will notify him to sign it a few days later after completing the record, indicating that it will handle it.

If the party concerned does not go, the public security organ may summon him by force. If the party concerned is the victim, it will be notified to sign, saying that the case has been handled, and it is necessary to sign the delivery receipt to confirm the receipt of the handling result. If it is a witness or other insider, the public security organ informs him to sign and say that he wants to change his testimony. At this time, the parties can choose not to go.
