City University student Ng Lung-ping, 18, and Choi Yuk-wan, 38, were granted bail at court on Monday after becoming the first people to be charged under the new mask ban.
Ng and Choi were accused of taking part in an unlawful assembly outside Kai Tin Shopping Centre in Lam Tin, which was held overnight between Friday and Saturday.
They allegedly used a facial covering that was likely to prevent identification without lawful authority or reasonable excuse in the early hours of Saturday, the day the anti-mask legislation came into force.
At Eastern Court, acting principal magistrate Cheung Kit-yee adjourned the case to November 18 at Kwun Tong Court, pending further police inquiry.
Cheung granted Ng and Choi cash bail of HK$300 (US$38) and HK$1,000 respectively, but imposed a travel ban and curfew on the pair. She also ordered them to report to police once a week.
More than 100 supporters packed the court building, where they chanted “no crime for facial covering. no justification for legislation” as they waited for the defendants to leave.
