In view of a growing trend of children being abandoned, the Government yesterday appealed to parents to seek help if they had problems caring for their disabled children. But social workers criticised the Government for not doing enough to make parents of handicapped children aware of the support services available. The claims came as police launched a search for the parents of a disabled child whose mother did not collect her from the Ebenezer Training Centre for the blind and mentally handicapped at Pok Fu Lam two months ago. The 13-year-old girl, Wong Yin-sum, is now in the care of a centre financially supported by the Social Welfare Department. The mother, Wong On-yuet, a divorcee, reportedly called the centre the day she disappeared and said she was in the mainland on missionary work. She also sent the centre her daughter's clothing after the phone call. The girl is blind and mentally handicapped. 'Everything shows the woman apparently wanted to escape and did not want her daughter back. Otherwise, she would not stop contact with the girl and the centre,' said Sergeant Ho So-ping. About 10 days ago, two mentally handicapped girls aged two and seven were abandoned in a McDonald's restaurant in Mongkok. A three-year-old mentally handicapped boy had also been dumped on a basketball court in Lam Tin last month. Six children were abandoned in the first six months of this year. A total of four were abandoned last year and five were dumped in 1994. The Social Welfare Department said parents could receive counselling and financial help if they found it difficult to look after their children. 'No matter what the circumstances, we hope the parents will not give up their children but come forward for help,' a department spokesman said.
