The police in Hong Kong say they will hold an inquiry to determine whether it was appropriate for an officer to fire two warning shots during unrest in Mong Kok.
Two handgun shots were fired into the air as hundreds of people clashed with police on Monday night.
The unrest began when officials began an operation to clear out unlicensed street food stalls.
More than 90 people, including police officers, were injured in the clash and dozens were arrested.
The unlicensed food stalls were set up for the lunar new year holiday and officials usually turn a blind eye to the hawkers’ lack of official permits, but this year decided to crack down.
Demonstrators prised bricks from the sidewalk to hurl at police, while others toppled street signs and set fire to rubbish bins in Mong Kok, a tough, working-class neighborhood just across the harbor from the heart of the Asian financial center.
The narrow streets in and around Mong Kok were the scene of some of the most violent clashes during protests in late 2014 to demand greater democracy for the former British colony that returned to Beijing rule in 1997.
