ONE driver was killed and another seriously injured when they were hit by a car as they argued over who was at fault in an earlier crash in Kwai Chung yesterday. Police said goods van driver Mr Wong Fu-cheong, 53, and car driver Mr Chung Pui-kwong, 33, jumped out of their vehicles after a minor crash on Kwai Chung Road outside the container terminal just before 4.30 am. As they were sorting out who was to blame, another car travelling in the same direction hit Mr Chung's Mazda 121, pushing it to the right before knocking them down. The driver of the third vehicle, a 24-year-old off-duty police constable, was also injured. The three were taken to Princess Margaret Hospital, where Mr Wong was certified dead at 6.20 am. Mr Chung was admitted in ill condition and later transferred to Queen Elizabeth Hospital. The constable was admitted in fair condition at Princess Margaret Hospital. Meanwhile, a young motorcyclist was killed when his machine was involved in a collision with a car near the Kowloon exit of the Eastern Harbour Tunnel last night. Mr Lam Chun-chi, 21, suffered serious head injuries and was certified dead on arrival at the United Christian Hospital. The accident occurred shortly before 8 pm when the car and the motorcycle were travelling in the same direction after coming out of the tunnel. It was reported that the motorcycle lost control after hitting the rear of the car and Mr Lam was thrown on to the concrete road divider. Traffic police in East Kowloon said last night that they are still investigating the cause of the incident.
