The demonstrator who was shot by police during Monday’s clashes between protesters and police in Hong Kong has been arrested on charges of “unlawful assembly.”

The 21-year-old student, surnamed Chow, is currently receiving treatment at a local hospital. He has reportedly been taken off sedation with his condition improving from critical to serious.

Footage of the gunshot fired into his chest has gone viral across international and Chinese social media. In the footage, a police station sergeant in Sai Wan Ho is seen grappling with another protester while pointing his gun at Chow as he advances towards him. When Chow appears to swipe for the gun, the officer shoots him in the chest.

In Monday’s other most sensational incident, a man is reported to have suffered burns to 44 percent of his body after being doused with a flammable liquid and set on fire for arguing with a group of protesters in Ma On Shan. He remains in critical condition.

That footage has also been widely shared, particularly by Chinese state media. You can watch it below, again viewer discretion is advised:

On Monday afternoon, Hong Kong Chief Executive Carrie Lam called demonstrators “rioters” and “enemies of the people,” singling out the man being burned as an “inhumane act that no one should condone” while calling it “unacceptable” for anyone to suggest that the police are out of control.

Chaos has continued to reign on Tuesday in the former British colony with protesters stopping blocking traffic downtown and throwing debris on train tracks as the city’s university campuses have turned into battlegrounds.
