Seven Hong Kong policemen were sentenced to two years in jail on Friday for beating a handcuffed activist after his arrest for assaulting officers during the Occupy Central movement in 2014 – an incident that shocked residents and weakened their faith in the usually trusted police force.

District court judge David Dufton said there was no justification for the assault, although he acknowledged that Hong Kong police had been working under great pressure to maintain order in the chaotic scenes back then.

Tsang said police and the government should take this opportunity to reform the monitor system and review the existing culture in the force, according to a report by South China Morning Post.
