Hong Kong has been through a difficult weekend as we learned with grief about the death of a 22-year-old university student, Chow Tsz-lok, on Friday -- the first death directly related to the city's protests over the past five months.
The news caused shock and sadness across the city, but also sparked new rounds of protests and clashes. On the night of Chow's death, from injuries sustained after falling from a third-storey car park a few days before, police officers fired a live round into the air in a densely-populated district in Kowloon, while tear gas canisters were used in Tseung Kwan O, where the tragedy happened.
