A 27-year-old Myanmar woman who had been trusted by a family in Singapore’s Choa Chu Kang area to look after their two daughters was arrested after allegedly abusing the girls physically while the parents were away at work.

The maid was hired by a 44-year-old woman of Vietnamese origin surnamed Nguyen to look after her two daughters, aged five and six, so that she and her 63-year-old husband could run a stall in a night market between 4pm and 2am each day, Lianhe Zaobao (Singapore) reported.

Initially, Nguyen had found the maid to be diligent and caring. But around two weeks ago the mother became suspicious when she noticed a bad bruise on her elder daughter’s forehead. The maid explained that the girl had fallen off her bicycle.

Last week the mother decided to go through footage from the home’s surveillance camera, and was shocked to see video of the domestic helper hitting her daughters on the head with spoons, a TV remote control, a pencil case and even a broomstick.

Though the girls were crying, the maid kept pulling their hair or pressing their heads against a table.

Police arrested the maid for allegedly abusing the two girls in her care. The accused was left in the custody of her employment agency.
