SINGAPORE - A 25-year-old administrative staff at a primary school secretly took eight videos of female staff using the toilet on two consecutive days.

On Thursday, Jondave Ong Han Wei was jailed for 24 weeks.

He pleaded guilty to four charges of insulting the modesty of a woman.

Another four counts of the same were taken into consideration during sentencing.

A district court heard that Ong was employed by recruitment firm People Advantage as a school programme executive, and did administrative work at Keming Primary School in Bukit Batok.

On July 1 last year, he went to a common staff toilet on the ground floor and attached his mobile phone to the sink pipe underneath the basin, using cable ties to secure the phone to the pipe.

He made sure the phone camera was pointing towards the toilet bowl, and switched on the camera's video recording function.

Between 9.46am and 10.08am, he recorded six women using the toilet.

He took three other similar videos at the same toilet later that afternoon. The longest video played for 32 minutes.

The next day, he again recorded four female staff relieving themselves at the same toilet.

At about 6.46pm, however, a staff spotted the camera and informed the police.

In all, the modesty of up to 35 women could have been insulted.

In mitigation, Ong, who did not have a lawyer, pleaded for leniency. He said his offence was out of character and told the court that he had apologised to the school staff.

For insulting the modesty of a woman, he could have been jailed for up to a year and also fined on each charge.
