Hong Kong democracy activists Joshua Wong, Agnes Chow and Ivan Lam have been jailed for organising and participating in an unauthorised anti-government protest last year outside the city’s police headquarters. Wong, who pleaded guilty at trial, has been sentenced to 13 and a half months behind bars. Chow and Lam will spend 10 and 7 months behind bars respectively. Their protest was a demonstration against excessive force being used by police.
