Sunday's marches took place in Tsuen Wan and neighboring areas. After the marches ended, violent protesters deviated from their routes to attack police officers.

Some radical protesters hurled bricks and petrol bombs at police officers outside Yeung Uk Road Market in Tsuen Wan. They also aimed strong light beams at police officers and setting up barricades to confront the police.

Protesters escalated their violence in the afternoon and evening. They blocked various roads in Tsuen Wan, paralyzing traffic in the vicinity.

Having given repeated warnings to the protesters in vain, anti-riot officers fired tear gas and used minimum force to disperse them.
