SIX policemen were yesterday found guilty of assaulting two customs officers and a decorator in Hunghom last February. In one of the largest courtrooms in San Po Kong Court, Magistrate Kwok Wai-kin delivered his judgment on the eight-week trial before more than 100 people. Sitting on a bench behind counsel Kevin Egan and prosecutor Michael Lunn, the six defendants listened attentively to the translation of the judgment by a court interpreter. They remained calm but appeared visibly disappointed after they learned of their convictions. The defendants, who had been in the force for between five and 19 years and with previous good character, have to wait until noon today for sentencing. The defendants had their bail extended until today and were led away by friends and supporters who used blazers to shield their faces from a crowd of press photographers. On trial were constables Cheung Kin-tak, 24, Tsang Yee-man, 26, Kevin Wong Chi-kin, 23, Lee Ching-cheung, 27, Cheng Wing-keung, 35, and senior police constable Ng Shiu-kwan, 39. Cheung, Lee and Ng were found guilty of common assault while Tsang, Wong and Cheng were convicted of assault occasioning actual bodily harm. The defendants had all denied the offences, which took place in the early hours of February 17. The victims were decorator Wong Kwok-hung, 25, and customs officers Yeung Hak-kwong and Tang Kwok-keung, both 28. Although Mr Kwok had described the case as an example of ''abuse of police authority'', Mr Egan said it was nothing more than a momentary and impulsive lack of judgment. While admitting that his clients had made ''an error of judgment'', he urged the court to impose a financial penalty on the three defendants who were convicted of common assault instead of sending them to jail. He said the consequence of the conviction of the three other officers who were convicted of assault occasioning actual bodily harm was ''horrendous'' - an immediate loss of their job, security, benefits and reputation. ''It's an established historic fact that nobody suffers more in a prison environment than convicted police officers,'' counsel said while urging the court to suspend any custodial sentence which may be passed on the three defendants. He said some of the defendants were only following what their leader (who had never been identified) did at the time of the incident. ''It would be wrong for them to be individually punished for the collective actions of all people involved,'' he said. It is the prosecution's case that Cheung assaulted Mr Wong during a routine stop-and-search operation by Cheung and his colleagues outside a Hunghom noodle shop. The Crown said the two customs officers then intervened over the rough way police were treating Mr Wong. Although this ended with a standoff and the customs officers returned to the noodle shop, the court heard additional police were later summoned. A confrontation developed between the two parties which escalated and reached a flashpoint when one police officer threw a bowl of noodles towards the customs officers and their friends. Tsang and Wong later assaulted Mr Yeung inside the noodle shop. Mr Tang was punched by Lee. Cheng struck Mr Yeung with a torch in the police vehicle while Ng struck him at the Hunghom police station, the court was told.
