A young man from Hong Kong was seen giving a water cannon truck the middle finger during a national security law protest on July 1.
Footage shows the man stood in the middle of the street where he gives the sweary gesture to the operators of the riot-deterrent vehicle.
The vehicle stops and the driver threatens to get out of the vehicle when the young man runs away.
The filmer explained: "Protests swept through the city, police deployed water cannons to end the protest.
"In the video, a young man gives the water cannon the middle finger." Part of the national security law sees subversion to the Central Government punishable with life imprisonment.
