DEFENCE counsel for a guard charged with beating Vietnamese boat people yesterday suggested witnesses had made up their allegations of assault. During cross-examination at Sha Tin Court, Paul Tse Tak-yan suggested the boat people had fabricated their stories as the result of a grudge against Correctional Services Department officer Cheung Foo-sang. Cheung, 35, has denied three counts of common assault, charges arising from an inquiry into the tear-gas raid on the Whitehead detention centre in April. Nguyen Van Lim, who has accused Cheung of beating and kicking him until he vomited blood, rejected Mr Tse's suggestion that inmates of section 7 at Whitehead made up their stories. Mr Nguyen said: 'The defendant did assault me so I'm just telling you the truth. I would not fabricate evidence against an innocent man.' The second witness, Nguyen Thi Thuy, also denied boat people embarked on a 'concerted effort' to set up Cheung. 'I have no personal grudge against Ty-Sir [the Vietnamese name for a young officer]. If he was innocent I would not frame him up,' she said. Mrs Nguyen, who is not related to the first witness, told the court Mr Nguyen clasped his hands and begged Cheung to stop beating and kicking him. She said Cheung ignored the pleas and continued to assault Mr Nguyen while other people cried and screamed for help. 'Ty-Sir grabbed him by the collar and then punched him in the tummy. I thought he felt a great deal of pain because he doubled up from the blow,' she testified. 'I shouted out loudly, 'Why is he so brutal?' ' The trial will resume on Monday, when excerpts of videos taken during the raid will be shown to the court. An application will also be made to defer until December a trial involving other officers charged with assault.
