Twenty-five people were injured when a bus veered on to a verge and overturned on Lantau yesterday. Tung Chung Road was blocked for about four hours after the accident at Shek Mun Kap at 8.15am. There were about 50 passengers on the bus travelling between Mui Wo and Tung Chung pier. Residents complained that the road was too narrow for traffic travelling in both directions. They said there was an urgent need to widen it before a tragedy happened. One passenger said: 'The bus swerved all of a sudden and veered on to the hillside. Then it overturned. People were screaming for help. They climbed out from the windows and the emergency exit. 'The bus was trying to avoid a car and then a street pole. It probably lost control before mounting the hillside.' The 25 people injured - 12 men and 12 women aged between 22 and 80 and a 12-year-old child - included the 54-year-old driver. They were sent to Yan Chai Hospital, Princess Margaret Hospital and Tung Chung clinic. All have been discharged, except for a 23-year-old man and 24-year-old woman, both of whom remained in Princess Margaret hospital in a stable condition last night. Ferry services were stepped up to carry passengers between Mui Wo and Central as well as Discovery Bay. Police said the bus swerved to avoid a car coming in the opposite direction then mounted the slope near Shek Mun Kap on the right-hand side before toppling over. Princess Margaret Hospital's accident and emergency unit chief of service, Dr Chiu Lai-hung, said the most serious case involved the 23-year-old man who had broken his arm. A spokesman for the New Lantao Bus company said the driver would be suspended until police had completed an investigation.
