A teenage girl died after a scarf she was wearing became entangled in the workings of a go-kart she was driving at a Tuen Mun circuit yesterday. The 15-year-old British girl was a student at an international school on Hong Kong Island, police said. She was apparently operating a rental kart when the accident happened just before 4.30pm at Diamond Coast International Kart Circuit, Lung Kwu Sheung Tan village. Police said she had been there with friends since about noon. She was taken unconscious to Tuen Mun Hospital where she was confirmed dead at 5.17pm. Lee Pak-ho, police assistant division commander at the Castle Peak division, said preliminary investigations found that she had been asphyxiated when the scarf around her neck became entangled in a wheel or other gear on the go-kart. Lee said: 'A witness at the scene said she was suddenly pulled to one side while driving. She was found with a scarf wound around her neck.' Police said her family was in Australia. Officers were conducting an examination of the site last night. A phone operator at the circuit, which was established in 2006 and is the only local site qualified for international races, said that people at the circuit were busy handling the case and made no further comment. Ricky Cheung, a veteran kart operator who has no association with circuit, said kart drivers, beginners and veterans, were required to wear specially designed protective suits, and no loose clothing was allowed. He said beginners were required to obtain temporary permits to operate a kart. They had to undergo training which included instruction on safety rules and suitable clothing, and take written and practical track tests. Cheung said it was not uncommon to see injuries from similar accidents involving hair or clothing tangled in kart engines at the rear of go-karts which were not usually covered, but fatalities were rare. A website for the circuit said children must be over 11 to drive a kart and must have a waiver of liability signed by a parent. Go-karts can reach a maximum 150 kilometres per hour. In January 2001, a 20-year-old female business student from Lingnan University in Tuen Mun was critically injured when her scarf was caught in a wheel of the kart she was driving at the Kart?dromo De Coloane in Macau. In a coma after suffering brain injuries, she was later transferred to Queen Mary Hospital in Hong Kong for treatment. A Home Affairs Bureau spokesman said the sport in Hong Kong was regulated by the Hong Kong Kart Club. A Transport Department spokesman said the department did not regulate the sport, while the Electrical and Mechanical Services Department said it did not regulate this type of vehicle.
