A resident of a building just opposite the underpass where the shoot-out took place told the coroner's court yesterday how he saw a passer-by ignore a cry for help from a fallen policeman and quickly walk away. 'The person was talking on a mobile phone and was walking towards the entrance of the underpass. I heard the echo of a call from a uniformed policeman saying: 'Help me, call the police',' Chow Chi-yung recalled. But the pedestrian was obviously shocked by what he saw and fled the scene by climbing over fences, he said. 'The person put away the mobile phone, walked towards to the fence and climbed over it,' he said. The person then crossed Canton Road, climbed the fence to get to the other side of the road and disappeared. Mr Chow, who lived on the sixth floor of Wai On Building in Austin Road, said he was awoken by the sound of gunshots at around 1.05am. He looked down from his bedroom window and saw a policeman in uniform, later identified as constable Tsang Kwok-hang. But as he continued to watch, Tsang gradually lay himself down on the stairs. Two pairs of feet - one pair wearing black leather shoes and the other with trainers - were opposite to Tsang, he said. Mr Chow said he heard a series of three loud gunshots, followed by a fourth about one second later. But he did not know how many had been fired when he was asleep. Another witness, Leung Kwok-kan, said he heard at least seven gunshots from the underpass. Mr Leung, a hair stylist who was doing some refurbishing work at his salon in Austin Road, was taking a smoking break at around 1.10am. 'It was very quiet at that time,' he said. 'Then I heard two or three shots, followed by a pause for several seconds. After that, I heard a series of five to six, or six to seven shots.' Mr Leung said he was frightened by the noise - which he believed was gunshots - and retreated back to the salon. Both Mr Chow and Mr Leung told Coroner Michael Chan Pik-kiu that they did not see anyone fleeing or getting into the underpass from Austin Road. But they said they were not sure if anyone had entered or left the scene from the opposite exit.
