HONG KONG — A Hong Kong student died on Friday after falling earlier this week from a parking garage where police officers clashed with protesters, a development that further escalated the public’s fury after months of antigovernment demonstrations.

Chow Tsz-lok, who was a student at the Hong Kong University of Science and Technology, sustained head and pelvis injuries when he fell one story early Monday morning . His death on Friday morning was confirmed by the city’s Hospital Authority.

Anger with the police has run high over the force’s widespread use of tear gas, pepper spray and batons on demonstrators during five months of protest. A key demand of the protest movement, which began over a now-withdrawn extradition bill, has been an independent investigation into the police’s use of force.

Thousands of people, including police officers, have been injured since the protests began in June, but despite the rising violence, no one has been killed in the clashes up until now. The police shot and wounded a demonstrator on Oct. 1 and another three days later in what they described as acts of self-defense.
