Security officials yesterday appealed to Malaysia to speed an investigation into a diving accident which left a Hong Kong fireman dead and his wife severely injured. Principal Assistant Secretary for Security Cathy Chu Man-ling told widow Lucia Leung Ka-hung, 37, yesterday the Government shared her anxiety about the slow progress and a diplomatic appeal had been made. Ms Leung lost her husband, decorated fireman Cheng Pui-man, 39, when a speedboat ploughed into them while they were diving off a Redang Island resort on April 9, 1998. A tendon on her right arm was severed and her face cut open. The wound needed 400 stitches. She claims the boat driver and the resort's managers were responsible. There is a three-year limit in Malaysian law to launch proceedings against the responsible party, according to Ms Leung's lawyer. 'We understand the anxiety of Ms Leung. Like her, the Hong Kong Government is equally concerned about the length of time taken to investigate the accident,' Ms Chu said. 'On her request, we have recently sent a representation to the Malaysian Consulate-General requesting the relevant Malaysian authorities to inform Ms Leung when the proceedings would be completed and have her right to seek compensations be safeguarded.' A two-day Malaysian court hearing started yesterday, Ms Leung said, and the Security Bureau would update her on the Government's response. 'We are rushing against time as the three-year limit is approaching. My deepest fear is that the Malaysian authorities are deliberately stalling and trying to sweep the whole thing under the carpet,' she said. 'We met Ms Chu, a very senior official and I am satisfied that the SAR Government is doing what it can to put pressure on the Malaysians.' Officials at the Malaysian Consulate in Hong Kong did not return calls.
