Joshua Wong, one of Hong Kong's most prominent democracy activists and among 47 people charged under a national security law, was sentenced to four months in jail yesterday for unauthorized assembly and violating an anti-mask law. Wong, 24, had pleaded guilty to both charges, including taking part in and using a facial covering at an unauthorized assembly in October 2019 during the height of anti-government protests, the court heard. He had faced a maximum possible sentence of three years in jail. The sentence will extend a 13-and-a-half-month sentence he is already serving for organising an illegal assembly.
