A 15-YEAR-OLD girl instigated an attack on about a dozen teenagers which left one of them with a severed hand and six others with cuts and slashes, the High Court heard. The attack in the early hours of September 19 last year at Hing Tin car park, Hing Tin Estate, Kwun Tong, was allegedly sparked by a quarrel. On trial before Deputy Judge Yeung and a jury are the 15-year-old girl, Lee Yin-mui, Choi Tai-wai, 22, Fong Chi-wai, 19, and Kok Chi-leung, 17, on charges of wounding seven teenagers with intent. Senior Crown Counsel Tong Man said the three male defendants all carried knives. Those who were attacked were unarmed. One had his right hand severed. When Choi was arrested he said under caution that he had been told that Lee had quarrelled with someone. He claimed he was told to go to the car park, but did not take part in the attack. The hearing continues.
