Warehouse owner dies in car crash on way to four-alarm fire A warehouse owner is thought to have suffered a heart attack before his car slammed into a lamppost as he was driving to a blaze at his Yuen Long godown on Sunday night. Chan Shu-wan, 57, was found unconscious in his vehicle after the crash and was declared dead in Pok Oi Hospital at 6.14am on Monday. He crashed his car in Tong Yan San Tsuen Road at 7.45pm on Sunday, about 45 minutes after his warehouse burst into flames. The crash site was about 800 metres from the scene of the fire. As there were no apparent injuries on the body, police are investigating whether Chan suffered a heart attack and lost consciousness at the wheel before crashing. A post-mortem examination would be conducted, police said. Officers from New Territories North traffic unit are investigating the case. The Fire Services Department is still investigating the cause of the godown blaze that took more than 140 firefighters over nine hours to contain. Emergency crews were sent to Tong Yan San Tsuen at 7.01pm on Sunday when the single-storey warehouse, which was being used to store plastic waste, burst into flames. The fire was upgraded to a third-alarm blaze at 7.29pm. Thirty-five fire engines and three ambulances were deployed along with nearly 150 firefighters and paramedics when the alarm was upgraded to category four at 8.37pm. Deputy Chief Fire Officer Leung Kwun-hong of the Fire Services Department said dense smoke and high temperatures had hampered efforts to fight the blaze. The blaze was brought under control at 2.16am and extinguished at 4.11am on Monday. There were no casualties. A spokesman for Fire Services Department said it was the first four-alarm blaze this year. Fires are rated on a scale of one to five according to their seriousness.
