A BABY found abandoned on Monday was yesterday made the ward of the Director of Social Welfare. The newborn girl is believed to have been abducted from Caritas Medical Centre last week and was later found in Yau Ma Tei. Results of definitive genetic tests will be available next week. The abducted baby's parents - Leung Wing-tat, 34, and Wong Yuk-ying, 32 - are convinced the abandoned child is theirs. However, government lawyers said there was not enough evidence to support the couple's claim and social welfare officials were instructed to apply for temporary custody. Mrs Leung said at home yesterday that she was desperate to confirm the baby was her daughter and take her home. She also expressed deep concern as to whether the baby would be well looked after by welfare officials. A Social Welfare Department spokesman said an appointed social worker would visit the baby at Kwong Wah Hospital and assume guardianship when the girl was allowed to leave. Government Laboratory scientists said blood grouping analysis and DNA test results would be available in four days. The results would be used to confirm preliminary blood tests conducted by Kwong Wah doctors which showed that the baby belonged to the Leungs. Kwong Wah's chief executive, Dr Kay Chiu-san, said the baby had recovered from a slight fever and her jaundice was being cured with phototherapy. Dr Kay said the baby was gaining weight and showed no problems with bottle-feeding. He had phoned Mrs Leung every day to update the couple on the baby's condition. The Leungs are also expected to meet Caritas doctors today to see if any medical and psychological assistant could be provided. The Leung's baby was abducted three days after birth by a woman dressed as a nurse.
