A JEWELLERY saleswoman who suffered serious injuries and says she lost her sex drive after she was knocked down by a bus is suing the Kowloon Motor Bus (KMB) company. A writ filed in the High Court says Yiu Lai-king, 30, even had to cancel her wedding plans because of her deteriorating relationship with her boyfriend of 10 years as a result of her injuries. Ms Yiu yesterday filed the writ seeking unspecified damages from KMB and Lam Pui-kuen, one of its drivers. The accident happened at night on September 2, 1997, as the bus driven by Lam mounted the pavement near the corner of Nathan Road and Mongkok Road and knocked her down. Father-of-two Chan Mou-man died after he became trapped under the wheels of the bus and about 30 people were hit as the bus struck a snack shop. Twelve people, including Ms Yiu, were injured. Lam was convicted of careless driving in North Kowloon Court on January 23, 1998. She was fined $3,000 and lost her licence for one year. After the accident Ms Yiu was taken to Kwong Wah Hospital, where her pelvis was found to be badly fractured and dislocated, requiring operations. While in hospital, she also suffered urinary and bowel complications as a result of her injuries, and she had to walk with crutches when she was discharged in December. She says pain in the lower part of her body made her lose her interest in sex, she suffered depression because of scarring and had problems walking. Ms Yiu's writ says she went back to her previous job in September 1998 but on a part-time basis. She became withdrawn and quiet, despite having been happy with her work and sociable and active before the accident. She had suicidal tendencies and often woke at night after having bad dreams, many about car accidents and being stranded in unfamiliar places. 'When she walks on the street she avoids walking along the side of the pavement. She dares not stand at bus stops,' the writ also states. She had problems with her boyfriend and they began to see each other only about once a week. Ms Yiu said she also became tired easily and began to feel she was being watched when she was walking with special shoes that she needed because her injuries had left one leg shorter than the other. The case will be heard at the Court of First Instance at a later date.
