SINGAPORE - On two separate occasions, a driver followed a woman he had spotted on the job into the toilet, and peeped at her from an adjacent stall.

Indian national Kuldip Singh, 27, used his mobile phone to film the first woman changing, but was caught after his second victim discovered him and raised the alarm.

On Friday, the peeping Tom was jailed for three weeks after admitting to criminal trespass and insulting the modesty of his two victims.

The court heard that on Oct 13, Singh had arrived with a colleague at 50 Science Park Road to collect chemical waste.

He followed his victim, a 37-year-old technical writer, into the female toilet but was caught after she spotted him and screamed for help.

Police later discovered a video clip in Singh's phone of someone changing.

Investigations revealed that some time in April, he had filmed an unknown victim in her underwear in a toilet at Ngee Ann Polytechnic.

Deputy Public Prosecutor Sruthi Boppana said Singh had "boldly ventured" into the female toilet to intrude on his victims' privacy.

Pleading for leniency, defence counsel Sarbrinder Singh said his client had done a foolish act. The lawyer added Singh was due to be married on Christmas day but the plan was off because of the case.

Singh, who pleaded guilty to two of four charges, could have been jailed for up to three months and fined up to $1,500 for each count of criminal trespass. He faced up to a year in jail and a fine for each count of insulting his victim's modesty.
