Police are investigating whether a man was ordered to get out of a taxi before he was killed by passing vehicles on one of the city's busiest roads on Saturday. Chow Kam-fat, 22, was seen walking unsteadily on the New Territories-bound inner lane of Tuen Mun Road at about 1.40am. Passing motorists called police, but they could not find him before he was killed. Elder brother Chow Shu-fat said yesterday that Chow had boarded a taxi after drinking with friends in Tsim Sha Tsui. He suggested his brother could have been ordered out of the taxi because of his condition. 'Why would a taxi driver drop him off halfway,' Mr Chow said at a press conference. 'That would be like giving him a death sentence. More tragedies can happen in the future if that is what drivers do.' Mr Chow's wife, Chan Nga-ting, asked tearfully: 'Even if he vomited in the taxi, how could someone ask him to get out on a highway?' Chow Kam-fat was last heard from when he answered a phone call from his girlfriend at about 2.05am, almost half an hour after he was reported on the road. Family members expressed anger that police took so long to find him after receiving the calls from motorists. Thought to have been hit by more than one car, he was certified dead at the scene. 'When he was hit by the first car, it might not have been fatal. If they didn't arrive so late he wouldn't have died,' Ms Chan said. 'Police received the call at 1.44am. If they made it to the spot at 2am, the tragedy wouldn't have happened.' Tyre marks were left on Chow's face and his four limbs were swollen, said the brother, who visited the morgue yesterday. The victim was the third child in the family. He lived in Tuen Mun with his elder brother's family and his two sisters, while his parents, who are fishermen, usually worked on a boat. He had worked for more than a year in the kitchen of a Tsim Sha Tsui restaurant. He went drinking once or twice a week with his colleagues, family members said. On Saturday, he was in a quarrel with some drinkers before his girlfriend accompanied him out of the shop. The two also argued and Chow took a taxi home alone. Police said initial investigation showed a taxi driver - who did not stop at the scene but called police later - had run over Chow. 'But we are still checking whether other vehicles hit the victim,' a police source said. Police were also checking whether the victim was ordered out of a taxi after vomiting, he said. Police rejected claims they arrived late at the site. It had taken them just 15 minutes to get to the spot where Chow was reported, but he had moved on from there, a source said.
