Firefighters believe the younger man died trying to save his father from the flames, which tore through their sixth-floor home at dawn A 50-year-old man and his 94-year-old father were killed in a fire in a flat in Tsuen Wan yesterday. Firefighters believe Leung Chung-on died trying to rescue his father, Leung Moon-yau, from the burning flat. The 94-year-old, a great-grandfather of seven, had walking difficulties and Chung-on, his youngest son, had lung disease. The two men were found dead in the father's room after the blaze. One was sitting on a sofa bed and the other was on the floor beside the bed. Another family member, Leung Ping-yin, 70, who lives with his wife in another of the flat's nine rooms, said he woke and discovered the blaze, which had broken out near the main door of the flat. 'I woke up my wife and we banged on the doors asking other tenants to flee. I also tried to fight the blaze with buckets of water but failed,' he said. 'I then realised that my father and younger brother might be trapped inside their rooms. I banged on the door of my father's room but no one answered. 'The fire spread very fast and the unit was packed with dense smoke. I thought they might have escaped and then I fled.' Leung Ping-yin blamed himself for the deaths, saying they might have been saved if he had not fled. He said his brother loved his father very much and might have tried to rescue him and become trapped. The Leung family occupied three of the rooms in the flat. A Fire Services team is investigating the cause of the fire, which raced through the top-floor flat and forced about 40 residents to flee the six-storey block in Sha Tsui Road at about 5.30am. A man living next to the burning flat climbed out of a window and stood on a 60cm-wide canopy waiting for help. He was rescued unhurt by firemen using a hydraulic platform. An elderly woman who lived in the flat said: 'I was awakened by the shouts of 'fire'. I had no time to put on my shoes. If no one had banged on the door, I would have been burned to death.' Six fire engines and two ambulances attended the scene, with 30 firemen taking about half an hour to bring the blaze under control. It was put out at about 7am. The Fire Services Department's New Territories South divisional officer, Li Kin-yat, said: 'The fire tore through the unit. Inside, all the walls were blackened and wooden partitions of the rooms were burned away, leaving the charred frames.' A tenant said an electrical switch box burst into flames, setting fire to a vacant bunk bed near the main entrance which was packed with newspapers, magazines, cartons and clothes. Electrical and Mechanical Services Department staff and government chemists were called in to check whether the blaze was caused by an electrical fault. Preliminary investigations showed there were no suspicious circumstances, Mr Li said.
