The Philippines government today said it needed more time to complete its official inquiry into a deadly hostage crisis that left eight Hong Kong tourists dead. The investigation, which began last week, was scheduled to finish on Monday before a formal report is submitted to President Benigno Aquino and Hong Kong authorities. However, Justice Secretary Leila de Lima today said the members of the investigating committee need more days to question witnesses as well as to re-enact the hostage drama that ended in a bungled police rescue. Two weeks ago, a sacked police inspector hijacked a bus full of Hong Kong tourists in a crazed bid to regain his old job and be cleared of extortion charges. The stand-off ended in bloodshed, when unprepared police commandos launched a flawed rescue attempt that left eight of the tourists dead. Hong Kong authorities have demanded a speedy and impartial investigation amid a public outcry and a chilling of ties between the neighbours.
