But he was dead by the time he reached hospital with five bullet wounds and signs of strangulation, says doctor Very weak signs of life were detected in the bullet-riddled body of Constable Leung Shing-yan when he was found lying in a pool of blood in a Tsuen Wan housing estate six years ago, the inquest into the death of Leung and three others heard yesterday. Law Po-tung, the first police officer to reach Leung after he was shot five times while investigating a bogus noise complaint, said the body was still warm and there was a very weak pulse. Constable Law, a close colleague of Leung at Lei Muk Shue police station, was giving evidence as the hearing resumed after a two-day break. The inquest also heard yesterday that a surgical mask was found at the scene of the shooting in Shek Wai Kok Estate - although none of the police and ambulance officers who attended the scene had worn one - and that Leung's neck bore signs of strangulation. Constable Law said that when he arrived at the death scene about 12.32pm on March 14, 2001, Leung was lying with his head in a pool of blood in a corridor on the fifth floor of Shek To House, near a fire door. There was a bullet wound near Leung's left eye. 'There was also a white surgical mask in the pool of blood underneath [Leung's] head,' he said. The court heard a statement by scientific evidence officer Lam Tak-keung that the mask, believed to have been worn by the attacker, had been taken for forensic examination. Sergeant Wong Chi-kwong, who arrived with an emergency team after Constable Law, said he could detect no sign of life on the seriously wounded constable when his team arrived at about 12.34pm. Sergeant Wong said he saw gunshot wounds near Leung's left ear and forehead and he noticed a red mark on Leung's neck which he believed was caused by strangulation. He said a mobile phone at one end of the corridor was ringing and he did not pick it up for fear of tampering with an important exhibit. He told his officers to stay calm and be careful after he saw Leung's service revolver, bullets and a speed loader were not in their pouches. 'I believed it was a shoot-out and the situation was very dangerous,' said the sergeant, who had immediately led his team to cordon off the area and search for the suspected attacker in the building. Leung was taken to Yan Chai Hospital and certified dead at 1.41pm by Willis Kwok Wing-hong, who said yesterday he believed the constable had died before he was sent to hospital. Dr Kwok said Leung had five wounds - which he believed to have been caused by gunshots - around the left eyebrow, the back of the head, the back of the neck, the left chest and left shoulder. Saying a mark on Leung's throat could suggest strangulation, Dr Kwok also said he suspected the shot in the head was fired from behind. Evidence from an X-ray examination revealed five suspected bullets inside Leung's body. Suspected fragments of bullets found in the corridor were seized for examination, the court heard yesterday. The court also heard that a packet of cigarettes, a credit card, warrant card, a Hong Kong Jockey Club electronic shroff card and other personal belongings were taken from Leung's body at the hospital by an exhibits officer. The joint inquest looking into the deaths of Leung, security guard Zafar Iqbal Khan during a robbery, and constable Tsang Kwok-hang and Tsui Po-ko, who died in a shoot-out in Tsim Sha Tsui last year, will continue on Monday.
