An elderly woman was killed after being struck by a car in Sau Mau Ping yesterday, while her husband narrowly escaped injury. Chao Toa-lang, 66, and her 75-year-old husband were crossing a pedestrian walkway along Sau Mau Ping Road outside Sau Fai House, Sau Mau Ping Estate, at about 3.30am when the accident happened. The driver, 33, lost control of his vehicle and hit the woman. His car then swiped a bus shelter and slammed into a lamp post, said Senior Inspector Law Hee-how of Kowloon East traffic unit. The woman was thrown into the air and suffered serious head injuries when she landed on the pavement. She was declared dead at United Christian Hospital. Chao, the mother of a marine police officer, was a cleaning worker. She was on her way to work at the time. The driver was arrested for dangerous driving causing death and was released on $5,000 bail. He is required to report back to the police in three months. He failed a breathalyser test, but the reading was below the level required for a charge of drunk driving. Five hours after the Sau Mau Ping accident, 18 primary school pupils and their minder suffered minor injuries when they were thrown from their seats as their school bus braked to avoid hitting a pedestrian in Tsing Yi. The driver was forced to brake abruptly when the man ran into Tsing Luk Street outside a bus stop at Tsing Yi Estate at about 8am. The pupils - seven boys and 11 girls aged between six and 11 - and their minder, a 37-year-old woman, were taken to Princess Margaret Hospital. They were discharged after being treated for shock and minor injuries. The pedestrian was not hurt.
