A man who pleaded guilty yesterday to a charge of dangerous driving causing the death of a policeman was full of remorse and had apologised to the victim's family, a court heard. The District Court was told the drunk driver's car collided head-on with the traffic policeman's motorcycle, sending the officer plunging 7.7 metres off a flyover onto a road below. Wu Wing-cho, 29, pleaded guilty to a charge of dangerous driving causing the death of police constable Chan Yip-shing, 28, on March 18. He also admitted to a charge of drink driving. In mitigation, barrister Alan So said the defendant felt deeply remorseful and had apologised sincerely to the victim's family. Wu had developed insomnia and psychiatric problems after the accident, Mr So said. Prosecutor Liu Yuen-ming said the accident happened at 4.30am as Chan was on his way to a traffic accident. He was riding a police motorcycle in the westbound lane of the Gascoigne Road Flyover near Wylie Road, Yau Ma Tei. Mr Liu said Wu's car went out of control, swerved from the eastbound lane and hit Chan's motorcycle. Chan was thrown from his bike, flew over the flyover railings and fell to the ground below. 'The way the defendant drove was far below [the level] of a competent and careful driver,' Mr Liu said. Chan suffered a double fracture of the skull, broken ribs and bruising over his whole body. He was taken to Queen Elizabeth Hospital, where he was certified dead upon arrival. The cause of death was given as multiple injuries. Wu and his wife, who was also in the car, were not injured. The driver of a passing bus saw Wu wobbling on his feet as he got out of his car, Mr Liu said. But he did not witness the accident. When police officers spoke to the defendant at the scene, Wu was unable to walk steadily and his speech was slow and slurred, the court heard. Wu told the police he had had a late-night snack in Tai Kok Tsui and was driving home to Hunghom. As he drove along the flyover, he saw a flashing beam of light in the opposite lane, hit his brake pedal and lost control of the car, hitting the railing. The police breathalysed Wu at the scene and found he was four times over the legal limit. Wu was taken to the Tsim Sha Tsui police station, where his alcohol level was found to be still three times above the legal limit. Judge Chua Fi-lan adjourned sentencing until Tuesday.
