Lawmakers yesterday urged the police to reveal the contents of investigation reports on the Manila bus hostage incidient, including details on 14 extra bullet fragments discovered by a forensics team on the bus. Following orders from the coroner's court, the police conducted an investigation and sent officers on four missions over the past two months to collect information on the hostage-taking, which left eight Hong Kong people dead. At a Legco security panel meeting, chairman James To Kun-sun said the investigation report compiled by the Philippine government suggested Hong Kong police had collected 14 bullet fragments from the bus where the shooting spree unfolded, after the Philippine investigation. Although he did not know how vital a role those fragments would play in revealing the whole truth of the incident, it showed the Philippine government was conducting the investigation in a 'casual manner'. Leung Po-tak, chief superintendent of the organised crime and triad bureau, said police had collected all the information they wanted, including statements from witnesses and medical and postmortem reports. They were waiting for three reports from trajectory and forensic experts. The coroner will decide whether to conduct a hearing based on the reports submitted. Undersecretary for Security Lai Tung-kwok said the government would urge the Philippine government to complete its trajectory report and state how brain-damaged Jason Leung Song-xue, 18, was injured.
