A MAN who allegedly committed arson at a Shekkipmei bank, killing four of its employees and seriously injuring nine others, tried to kill himself on the eve of his court appearance in North Kowloon Court yesterday. Police said Chu Po-kwong, 32, leapt from the bunk in his detention cell in Shekkipmei police station and smashed his head against a wall. A policeman managed to restrain him before he did himself any serious injury. Chu was taken under guard to Queen Elizabeth Hospital for X-rays and a check-up. He suffered only minor bruising but was detained in a special custody ward overnight for observation. The suicide attempt occurred at 8 pm on Tuesday, just hours after Chu was escorted back to the scene of the alleged crime for a reconstruction. Yesterday's court hearing was delayed by about two hours until 11.30 am, when doctors decided Chu was fit to attend court. Chu, who had a dull look and messy hair, appeared calm in the dock. He said he did not need a duty lawyer. There were no apparent signs of injury to his head, although he had a white bandage on his bloodstained right hand. Chu is charged with murdering Chiu Lo-mui, 33, Kan Yip Yuk-fong, 45, Lui Sau-chu and Tsang Liu Pui-kee, both 26, at the Hongkong Bank branch in Nam Cheong Street, Shekkipmei, on January 10. He is also charged with arson. No plea was taken. Magistrate William Eccleton adjourned the case until January 26, and remanded Chu in custody.
