Investigation launched into high-speed collision that leaves taxi driver dead Police are investigating whether a van carrying officers to an incident was trying to speed through a red light when it slammed into a taxi, killing the taxi driver and injuring three policemen. The police van, travelling along the New Territories-bound lane of Kwai Fuk Road, Kwai Chung, on its way to the scene of a suicide attempt, crashed into the taxi at the junction with Hing Fong Road. The van spun and mounted a road divider before coming to a stop, Superintendent Law King-fu, of the New Territories South traffic unit, said. The impact pushed the taxi into a Kowloon Motor Bus single-deck bus stopped at a red light in the Kowloon-bound lane of Kwai Fuk Road. The taxi driver, Chan Hoi-chak, 55, and a constable who was a front-seat passenger in the van were trapped in the wreckage and had to be freed by firefighters. Both were taken to Princess Margaret Hospital, along with the other injured policemen. Chan was declared dead 21/2 hours after the accident, which happened at 3.30am. Mr Law said officers were still investigating whether the police van or the taxi had been trying to run a red light at the time of the crash. He said emergency vehicles, including police vehicles, were allowed to run red lights in emergencies and motorists had to give way. Urban Taxi Drivers Association Joint Committee chairman Kwok Chi-piu said: 'I understand that emergency vehicles in response to urgent calls have to slow down and check the road conditions before they run lights.' The injured policemen, aged 29 to 39, were stable in hospital last night but were not yet able to give statements about the crash. The driver of the van passed a breath-alcohol test with a zero reading. Both vehicles were removed for examination. Fellow officers sent to deal with the suicide attempt found a woman had taken an overdose of pills. She was taken to hospital and survived. The accident was the first of two yesterday involving emergency vehicles at red lights. Just before noon, a motorcyclist suffered arm and leg injuries when he fell trying to avoid a fire engine in Fanling. Police said preliminary investigations showed both the police van and the fire engine had their sirens and flashing red lights operating when they crashed. The Fire Services Department said the fire engine was answering a call to an old people's home that turned out to be a false alarm. Police asked witnesses to the Fanling incident to contact them on 2611 3200 or 2611 3320.
