SIX people, including two women and a schoolboy, are suing four police officers for damages for assault and battery. In a writ filed in the Supreme Court, the plaintiffs are also claiming damages for false imprisonment and for malicious prosecution in February 1990. At a press conference held the day after the incident, the plaintiffs claimed they were assaulted by police with batons and were treated and discharged from Princess Margaret Hospital. The group claimed they stopped their car near the Tsing Yi roundabout in the early hours of February 11 because a male occupant felt ill. They were then approached by the police officers, who handcuffed and assaulted them. The plaintiffs are Ms Cheung Mei-po, 19; Ms Chan Mei-ling, 29; schoolboy Chan Chun-ming, now 16; his brother, Mr Chan Chun-chung, 23; Mr Chu Hoi-luen, 31; and Mr Lam Chun-leung, 21. The officers are Mr Lee Chi-wo, Mr Siu Kwok-hang, Mr Chan Ming-sum and Mr Liu Chi-kin. The Attorney-General, on behalf of the Crown, is also named as a defendant.
