The man aged around 50 surnamed Cheung was said to be a triad member, Apple Daily reported.

Cheung, who appeared to be drunk, hit the hood of the police vehicle, pointed at a female sergeant and two officers who were inside it, and yelled, “Leave!”

No one got out of the vehicle, or make any attempt to restrain the man. They just drove away slowly.
