A quarrel over television noise ended in violence yesterday when a father attacked his son with a chopper. The son, 19, and surnamed Liu, suffered a wound to his left wrist. He was taken to the Princess Margaret Hospital, where he was in a stable condition last night. His 63-year-old father was arrested for wounding. A police spokeswoman said the attack was the result of a recurring dispute in the Kwai Chung public housing flat. 'They had quarrelled the night before about excessive noise,' she said. 'The son had thrown an electric fan at his father and injured his left arm. 'They then had another argument over television noise. The father was still angry about it [yesterday] morning and allegedly attacked the son with a chopper.' The attack happened at 12pm in their public housing flat at Yan Shek House, in Shek Yam Estate. 'Both had left the scene after the attack and passers-by reported the case to the police after spotting the victim and his injuries,' the police spokeswoman said. 'Officers located the father at a restaurant nearby and arrested him there.' Police investigations are continuing.
