A businessman accused of involvement in a multimillion-dollar fraud case killed himself in his cell just hours after urging his wife to fight to clear their names, the Coroner's Court was told yesterday. Yip Hiu-sui, 46, was discovered hanging by a blanket from the window of his cell in the isolation unit of the hospital at Lai Chi Kok reception centre on January 25. A jury yesterday found he had committed suicide. Yip, a director of Fountain Datacom, was accused along with his wife Tang Wai-na, vice-manager of mainland food conglomerate Guangnan (Holdings), of defrauding banks with false letters of credit. He and Tang were two of the six defendants in the fraud case who appeared in Western Court on January 17. The six had been charged with misappropriating $66.8 million. Yip had been remanded in custody at the Lai Chi Kok reception centre after appearing in court and was waiting for the case to be transferred to the High Court. Correctional Services Department officers told the Coroner's Court that Yip was distressed and emotionally unstable during his time in the centre. He had been interviewed twice by psychiatric officers on January 24 after displaying abnormal behaviour. 'He accused Hong Kong's legal system of being unfair and said he could not get a lawyer to represent him in court,' psychological unit officer Eddie Lin Yin-pui told Coroner Andrew Chan Hing-wai. 'We told him he could apply for lawyer services through legal aid and explained to him the procedures of how to apply.' Mr Lin said Yip left the office in high spirits. That day he wrote to his wife, urging her to 'live on and fight to clear their names'. 'If you die, our names would be forever tarnished and the truth would be lost. I am applying for legal aid to get us a legal representative - we must break the blockade,' Yip wrote. He was found dead early on January 25. Hospital doctors certified his death before an ambulance arrived. The charges against the six defendants alleged false letters of credit were submitted to the Bank of East Asia, Sakura Bank, Rabobank and ABN Amro Bank, purporting to show commercial transactions between the now insolvent Guangnan company and other firms. The jury yesterday recommended that the Correctional Services Department provide full-day psychiatric services to prisoners.
