Violent protestors gathered in Hong Kong's Tuen Mun to block roads, and even threw a petrol bomb to a restaurant on Monday night.
Starting from 8:30 p.m. local time, a group of violent protestors gathered outside the Tai Hing Operational Base in Tuen Mun, shouting and aiming laser beams at police officers, the Hong Kong police said in a statement.
They also blocked Leung Wan Street with removed railings and traffic cones, affecting the traffic at scene.
At around 10:00 p.m. local time, the rioters started vandalizing a housing estate nearby. Some rioters broke the glass window of a restaurant with bricks and then threw a petrol bomb into the restaurant, causing dense smoke at scene. In addition, rioters set up barricades and set them on fire in the housing estate.
The police deployed tear gas for dispersal as the mobs' actions seriously endangered the safety of those present and nearby residents, the statement said.
Condemning all violent acts, the police warned the rioters to stop the illegal acts immediately.
