A MAN remanded in custody for three months over a murder he did not commit said yesterday he had gone home to find his wife in bed with another man. Chronic alcoholic Lau Chi-kin was convicted in the District Court yesterday of throwing a corrosive fluid over his wife with intent to cause grievous bodily harm. He had told the court his wife had thrown sulphuric acid over herself to cause trouble for him. It burned her right forearm, left upper arm and right cheek. Lau said yesterday he had surprised Yuen Yuet-or on August 5 last year several days after his release, confirming his suspicions that she had been having an affair. Two weeks later, he had found another man's underpants at their home and challenged her about them. Ms Yuen, a former nightclub hostess, had lost her temper and called him ''old, penniless and a prisoner''. Unemployed Lau, 39, denied that he then threw the acid over his wife. He said his wife had assaulted him nine times during their three-year marriage. On five occasions he needed hospital treatment. Deputy Judge Barnes adjourned sentence for medical, psychiatric and psychological reports. Defence counsel Joseph Tse stressed that Lau was found not to be involved in a murder and had been released unconditionally without charge. Another man now faces a murder charge.
