THE United Nations human rights committee may be asked to investigate the death of a murder suspect who died last month in police custody. The chairman of Hong Kong's Human Rights Commission, Ho Hei-wah, said the case could be submitted to the committee, which might demand an explanation from the Government. Mr Ho is also pressing for an independent inquiry into Lam Tin-ming's death after an initial postmortem examination found broken ribs, a torn liver and bruising to Lam's feet and chest. His comments follow a second postmortem examination last week by a pathologist flown in from Britain. The examination reportedly suggested Lam, 56, died of a heart attack. Police were unable to release details last night. A police spokesman said: 'The pathologist has given a copy of his report to the coroner, but the police have not yet seen a copy.' Mr Ho said the committee was concerned about police powers and several members were already planning to visit Hong Kong. The trip would be a good opportunity for them to press for a detailed probe into Lam's November 24 death, he said. Legislative Council security panel chairman James To Kun-sun has asked Secretary for Security Peter Lai Hing-ling for a meeting on the death but has not yet had a reply. 'Whether we ask for an independent inquiry depends on the coroner's inquest, but the public is very concerned,' he said last night.
