Ex-teacher pleads guilty to filming schoolgirls in toilet

A former teacher who was charged in February for installing pinhole cameras in the female toilets of the school he was teaching at pleaded guilty this morning, saying that he wasn't in the right state of mind when he committed the deed.

Bertrand Ngien Wen-Tseah, 37, was a science teacher at Yuhua Secondary School and is expected to be sentenced for one or two years on July 25 for his shameless deeds and destroying the evidence.

The 37-year-old had trespassed the school's female toilet in February where he installed three pin-hole cameras in each of the three cubicles behind the cubicle walls, according to court documents.

On the same day, Ngien realised the cameras had been discovered by a colleague and tried to steal the micro SD memory cards.

He was found out by school authorities a few hours later and was asked to return to school.

On his way back to school, Ngien threw the memory cards into the canal in Jurong West. He then met the principal, vice-principal and senior teachers and was told a police report would be made.

In further attempt to get rid of evidence, Ngien threw the laptop issued to him by the Ministry of Education down the rubbish chute at his Clementi home at night.

He had used the school laptop to view footage of older videos of the girls using the toilet.

If convicted of insulting modesty of a woman, Ngien could be jailed up to a year and fined.

For destroying evidence, he could be jailed up to two years and fined.

Ngien also faces a maximum jail term of one year and a fine, for committing mischief.
