January 7, 2020, the Yuen Long District Council took a vote in its first meeting of the new term to set up a working group to probe into the 721-mob-attack incident, and also to demand answers from the police.
The attacks took place at the West Rail Station, late in the evening of the 21 July 2019. About a hundred white-clad assailants, with suspected triad background, attacked commuters at the concourse of the station indiscriminately. The police force faces accusations that it colluded with the assailants after they took almost 40 minutes before any officers arrived at the scene.
After a landslide victory in the District Council election last November, the council is now dominated by pro-democracy members. They are demanding that the government set up an independent inquiry to investigate and look into the police brutality.
