How long after the incident? If you don't report it, you won't pursue it.
If you are suspected of a criminal offence, the reporting time is not limited by time, but the time is too long, and I am afraid that the public security organs will not be able to investigate clearly. If you don't understand anything, you can continue to ask questions or for more details, please visit Weihai lawyer portal: www.wh-lawyer.com; If you think my answer is helpful to you, I hope it can be adopted and praised.
