Jailed Hong Kong opposition activist Joshua Wong has been handed another prison sentence, this time for four months, for joining an unauthorized rally and flouting a government-imposed mask ban over a year ago. Eastern Court on Tuesday sentenced the 24-year-old on charges arising from a demonstration on October 5, 2019, when hundreds of people marched from Causeway Bay to Central in protest against a government-imposed mask ban, which came into effect that morning. His co-defendant, 75-year-old veteran activist Koo Sze-yiu, who took part in the same rally, was jailed for five months, just six days after he completed his jail term in a separate case.
