A baby girl whose two-year-old brother died from alleged abuse will be separated from her mother, it was decided yesterday. The Social Welfare Department said the 21-year-old mother had paid inadequate attention to her children and was not suitable to care for Yu Ching-sze, her one-year-old daughter. Ching-sze's brother, Ching-kong, died last Wednesday in Yan Chai Hospital in Tsuen Wan. The boy, who would have turned three next month, was admitted to hospital after his mother found bruises on him. He suffered internal bleeding and peritonitis, and his duodenum was burst. Social workers, police and psychologists ruled yesterday that child abuse was evident in both cases. A department spokesman said it would apply to the court for a child protection order for Ching-sze. He said it had yet to be decided how long the baby would be in their care, adding she may be placed with a foster family or in an institute. The department would review the mother's state and social workers would try to teach her child care techniques and examine her housing needs. Ching-sze was physically abused by her mother's previous boyfriend. The department believed she was safe after the abuser was jailed. The girl is in hospital for care and observation. Andy Yeung Ming, 23, appeared in Tsuen Wan Court last week charged with murder. The case was adjourned until January 25.
