Will the crime of helping the letter be investigated online?

If it constitutes a crime of helping the letter, the public security bureau has a large amount of evidence and may be arrested. If you escape at this time, then the Public Security Bureau may pursue it online. Online pursuit shows that the police have filed a case for investigation, but they have not yet been convicted. Conviction can only be decided by the court. It doesn't necessarily mean that people who are chased online will be convicted. It depends on the evidence of the case. If the evidence is insufficient or the court thinks that it does not constitute a crime, it will not be convicted.

If the people's procuratorate and other departments decide to take technical investigation measures and hand them over to the public security organs for execution, the public security organs at or above the municipal level with districts shall go through the relevant procedures in accordance with the provisions and hand them over to the departments responsible for technical investigation for execution, and notify the people's procuratorate and other departments of the implementation.
