Thousands of people across Hong Kong held vigils on November 8 for Chow Tsz-lok. The 22-year-old computer science undergraduate studying at the Hong Kong University of Science and Technology had died earlier that day. Chow had suffered a severe brain injury after he reportedly fell four metres (13 feet) at a car park in the early hours of November 4. The incident happened as police in the area were firing rounds of tear gas to disperse a crowd.
