Hundreds of Hongkongers gathered in Tseung Kwan O, Hong Kong on March 8, 2020, to pay tribute to Chow Tsz-lok, a second-year computer science student at Hong Kong University of Science and Technology, who died of a severe brain injury suffered in a one-storey fall in a car park in November last year.  Police said they seized petrol bombs, bricks and other protest items from the car park where the memorial was held.
