Defence lawyers for seven policemen accused of beating up activist at Tamar Park during Occupy protests, have cast doubt on the victim's identity, asking it was Ken Tsang at all.
The defence, making their final submissions, said that the allegations against their clients cannot be substantiated.
The key piece of evidence in the trial is TV footage of a man being carried off to a dark corner of Tamar Park, where he was kicked and punched by a group of people.
One lawyer said many people wore similar clothes on the night in question, and the court shouldn't try to identify anyone based on his clothing.
He also said Tsang could have sustained his injuries earlier, while he was being subdued by officers.
Another lawyer told the court that his client had tried, but failed to stop the assault.
The seven are jointly charged with inflicting grievous bodily harm to Tsang with intent. One of the defendants is also accused of assaulting the protester in a police station later the same night.
