At least two parents have lodged police reports against NTUC First Campus, following Sunday's arrest of a part-time teacher from NTUC My First Skool centre in Toa Payoh. The 51-year-old teacher was arrested for allegedly mistreating a three-year-old child by dragging him across the floor and pushing him onto the ground last Friday.

A mother, who only wanted to be known as Mrs Loh, said that she sends her sends her 2 1/2-year-old son to the childcare centre and was present at a briefing for parents on Monday morning. About 10 parents went for the briefing, and two of them had lodged police reports against NTUC First Campus, said the 37-year-old who is self-employed and runs an online art and craft business.

"Their kids had bruises and scratches on them, so the parents decided to make police reports so that police would investigate to see if these are cases of abuse," she said.

Police investigations of the incident on July 5 are ongoing. Mrs Loh said parents at the briefing were also informed that the childcare centre will look at closed-circuit television footage from the past 28 days, to see if there have been other cases of teachers abusing children. NTUC First Campus met the teacher earlier on Monday as part of an internal probe. It will give more details on Monday evening.
