An architect is thought to have fallen to his death while trying to stop an unemployed friend from jumping off a public housing block yesterday just hours after he was honoured at an awards ceremony officiated by Chief Secretary Henry Tang Ying-yen. The bodies of Leung Kam-kong, 28, and Chan Kei-tai, 27, friends since school, were found a short distance apart at Kwun Lung Lau estate, Lung Wah Street, Western, at 1am. A resident called police after hearing two loud bangs and seeing the bodies. Officers believe the pair fell from the public corridor on the 19th floor of the Block F, where slippers belonging to one of them was found. Neither lived on the estate but Chan had lived there as a child. Police believed the former office worker was suicidal because he had been jobless for a few months and had recently split from his girlfriend. 'Our assessment at this stage shows that one of the two men tried to prevent the other falling. In doing so he fell,' a police source said. Leung, who worked at the firm Urbanage International, was described last night by his boss, William Tseng Yen-wei, as a 'very talented and up-and-coming' employee. Mr Tseng said he was shocked by news of Leung's death and could not believe he would commit suicide. Leung had just won an honourable mention with three colleagues in the 'World Exposition 2010 Shanghai China - Hong Kong Pavilion Concept Design Competition' and had been very happy at the award presentation on Monday hours before his death. A relative said Leung, the oldest son in a family of six, turned down a scholarship to further his studies in Australia and returned home in January to look after his disabled father and family. He worked in Chai Wan and had a degree in architecture from the University of Adelaide, Australia. His relatives burned paper offerings in a ritual outside the building in yesterday afternoon.
