Hong Kong police on Wednesday night arrested a 57-year-old woman suspected of abusing an eight-month-old boy who has been under her foster care in Kwai Chung, New Territories.

The boy was born in April last year but his mother was in a correctional institution. He had been under the care of a foster family until November before being transferred to another foster family in Kwai Chung, Oriental Daily reported.

The new foster family has three members, a 59-year-old man, a 57-year-old woman and their daughter aged around 30. They had had a good record of taking care of at least 10 foster children before.

On January 5, the foster parents found the boy had vomited, and they sent him to Prince Margaret Hospital, Sing Pao reported. Medical staff found bleeding in the boy’s brain, which could have been caused by being badly shaken. They reported the case to police.

It was understood that the boy was unconscious when he was admitted to the hospital and was declared in critical condition. After staying in the pediatrics intensive care unit for five days, the boy is now in stable condition.

After initial investigation, police officers from Kwai Ching Station arrested the foster mother and confiscated the child’s crib and some infant products for further investigation.
