The teenager who was involved in a New Year's Eve slapping row with police officers that was captured on TV was last night arrested for allegedly punching and biting a warden at a boys' home. Lin Chi-wai, 15, has been staying at the home in North Point since February. His parents had applied to a court under the Child Protection Ordinance for their son to be held at the boys' home because they said they could no longer control him. Police said Chi-wai was chasing another boy in the dining hall of the home at 6.45pm when the incident happened. When a 39-year-old warden intervened, Chi-wai allegedly punched him in the eye and bit his hand. He was later overpowered by other wardens. Both Chi-wai and the warden were taken to Eastern Hospital, where the teenager was arrested for assault after a doctor inspected him. Chi-wai became the subject of huge media attention when the New Year's Eve confrontation with two police officers was caught by TVB cameras. Footage showed the Secondary Three student apparently exchanging slaps with two policemen in Tsim Sha Tsui. His mother later filed a formal complaint with the Complaints Against Police Office against the two officers, saying she felt that they had used unnecessary force on him. She claimed they had pushed Chi-wai and grabbed his neck. He had responded by 'returning a few pats'. She also said unfair comments had been made about him on radio chat shows. The police insisted no force was used and the officers were only trying to stop him picking up fluorescent sticks to throw.
