A nine-year-old girl was found hanged in her Kwai Chung home last night. A police spokeswoman said the mother found the girl, surnamed Wong, hanging by a rope from a window in her bedroom at the family flat in Ying Kwai House, Kwai Chung Estate, at 7pm. Her mother untied her and called an ambulance. The child was rushed to Yan Chai Hospital where she was declared dead. Police did not say whether the case was suicide. They classified the case as 'person found hanging'. The 38-year-old mother was assisting police with their investigation last night while the father remained at the hospital. Wong Chung-kwong, chairman of the Whole Person Education Foundation, said it was tragic to see a child so young losing his or her life and he urged more attention to be paid to mental health. The psychologist said a child of this age could be facing stress from troubled relationships with parents or from study. Dr Wong said: 'This case maybe tells the city it should pay more attention to mental health, as well as children's emotions.' Keswick Chuk Wing-hung, a social worker at the Evangelical Lutheran Church of Hong Kong, said such cases might be avoided if society was more aware of mental health. If the case is classified as suicide, she would be one of the youngest to kill herself by hanging in Hong Kong. A boy of eight, hanged himself in his Fanling home in June 2003, after his father scolded him over homework.
