The prosecution on Monday wrapped up its case against seven police officers accused of beating up former Civic Party member, Ken Tsang, during the Occupy protests in October 2014.
They are facing charges of causing grievous bodily harm to him with intent. One of the officers is also accused of assaulting Tsang in a police station afterwards.
In making his final submission in the District Court, the prosecutor, Daniel Marash, said the defendants had carried zip-tied Tsang to a dim corner at Tamar Park, where he was allegedly punched and kicked. He said Tsang was in a vulnerable position and had no way to protect himself.
Marash said that although one might not be able to pinpoint which injury was caused specifically by which of the defendants, and that some had acted as look-outs, the seven officers had acted as a "joint enterprise".
Counsel also noted that some police cars were parked near where Tsang was first subdued, but the defendants took a detour and took him to the dim corner.
Marash said this showed they had the intention of assaulting him when he was already under restraint.
He went on to say that the seven had "acted outside their lawful power" when they used force on Tsang.
The defence will begin its final submission on Tuesday.
