Hong Kong leader Carrie Lam warned protesters that violence wouldn’t help achieve their goals as the Asian financial center reeled from a tense day of citywide protests that saw a demonstrator shot, another man set on fire and tear gas waft through luxury shopping malls.

The protests, which erupted anew Friday over the death of student last week, carried into the work week Monday, with activists seeking to disrupt business and transportation networks. In the chaos, a 21-year-old protester was shot by police, while another man was set on fire during an argument with a group of people in the northeastern area of Ma On Shan.

Monday’s flare-up comes after a weekend of rallies in the wake of the student’s death from injuries suffered near a protest last week—the first fatality directly tied to police action in months of unrest. The historic demonstrations began after the government proposed now-withdrawn legislation that would have allowed extraditions to mainland China. The movement has since expanded to call for greater democratic accountability, as well as an independent inquiry into the violence.
