A BUILDING site worker used beef knives in a 'cowardly attack' on two men after a row over a finger-guessing game. Judge Sweeney sentenced Yuen Chun-po, 24, to 18 months' imprisonment. 'Society would be alarmed if people who resort to beef knives to settle childish disputes were to walk free because of previous good character,' he said. Yuen admitted two charges of wounding with intent. Prosecutor Penelope Wacks told the court the victim, Chan Chi-sing, met the defendant and an unknown man in a bar in Mei Foo Sun Chuen at about 7.30 pm on April 15 last year. Yuen suggested Mr Chan and his friend, Hui Wai-pong, played Chai Mui, a finger-guessing game, the District Court heard. They played until 3 am, when Yuen and the unknown man left the lounge after a dispute. After 30 minutes, they returned and asked Chan to leave the bar. Outside, they took beef knives from a taxi and attacked him. A waiter at the lounge, Hung Chong-chi, tried to intervene but was also chopped on the head and back. Mr Chan had cuts to his arms, chest and back and was off work for about two weeks. Yuen gave himself up at Cheung Sha Wan police station three months later. Stuart Mason-Parker, for Yuen, told the court Yuen had been drunk when he committed the offence and felt remorse for what he had done. Judge Sweeney accepted Yuen might have acted out of character.
