SINGAPORE - A man who took photos of a woman's underwear with his mobile phone at an MRT station on three separate occasions was jailed for three weeks on Wednesday.

Malaysian Daniel Chin Jun Kent, 21, then a room service crew, admitted to two counts of insulting the modesty of the 24-year-old woman at Bayfront MRT Station on May 14 and July 2 this year.

A court heard that the woman was standing on the ascending escalator at Bayfront MRT Station on her way to work on May 14 when Chin found her sexy and took a photograph of her underwear with his mobile phone without her knowledge.

On July 1, he saw her again at the same station and wanted to take upskirt photographs of her. He was standing two steps behind her on the escalator when he intruded into her privacy. He used his mobile phone to take a rapid shot of six photographs of her underneath her skirt.

As he was doing this, his hand holding onto his phone had accidentally stroked the back of the victim's thigh. She turned around and asked what he was doing. He replied he was not doing anything.

As they were walking to their workplace, she asked for his name, and he gave it to her.

Chin subsequently felt worried that the victim would report him and that his mobile phone would be checked. He then deleted all the photographs taken of the victim when he was at work.

The victim lodged a police report the next day.

Chin, who had four other similar charges considered during his sentencing, asked the court not to jail him and to give him a chance.

District Judge Christopher Goh said that as he had said in previous similar cases, people caught for such offences must expect to bear the full brunt of the law.

He noted that Chin had committed the offence against the victim three times.

Chin could have been jailed for up to one year and/or fined on each charge.
