They were suspected of attempting to pervert the course of public justice, accessing to computer with criminal or dishonest intent, criminal damage and illegal gathering, according to Chan.

Lam was also suspected of participating in a riot on July 21, 2019 in Yuen Long. He and 12 other male suspects were arrested by the police over the incident, Senior Superintendent Chan said, adding that the accusation of so-called collusion between the police and the triads in the Yuen Long incident was untrue.
