A newly recruited bus driver was arrested on suspicion of dangerous driving yesterday after he lost control of his double-decker and crashed, injuring 15 people in Tai Kok Tsui. A preliminary investigation showed that the Kowloon Motor Bus vehicle could have been travelling above the speed limit of 50km/h at the time of the accident, police said. Schoolgirl Wong Shun-yan, 13, narrowly escaped death when she was knocked down by the bus and dragged for a few metres along the pavement in Tai Kok Tsui Road, police said. The Form Two student was trapped beneath the bus and had to be freed by firemen. She was in serious condition last night in Kwong Wah Hospital. The others injured were the bus driver, 47, and 13 passengers including seven students aged between nine and 13. The driver and a female passenger, 38, were in stable condition in hospital while the others were discharged after treatment. The route 12 bus was heading for Tsim Sha Tsui when it spun out of control turning into Tai Kok Tsui Road from Cherry Street at 7.49am. It rammed into a central divider and crossed three lanes before mounting a pavement. Shun-yan was knocked down by the bus while waiting for a minibus. 'The bus drove onto the pavement and hit the girl before it slammed into the concrete pillar of the building and came to a stop,' Chief Inspector Leung Sing-fai of the accident investigation unit of Kowloon West police said. He said the driver was arrested for dangerous driving because 'initial investigation showed that he was driving fast and his driving manner was dangerous at the time'. The man was being detained by police in the custodial ward of Queen Elizabeth Hospital and no charge had been laid last night. He has had a private car licence for about five years and was a restaurant worker before joining KMB last month. KMB has suspended him from driving pending the results of an internal investigation. Asked whether the bus company would review training for its new drivers after the crash, a KMB spokeswoman said: 'We have comprehensive training for our new drivers and conduct regular reviews to see if there is any room for improvement.' KMB said the 12-year-old bus passed an inspection on Saturday.
