SINGAPORE - A supermarket manager who used his mobile phone to record a colleague changing in the toilet was jailed for 12 weeks on Wednesday.

Pang Sou Bak, 30, was working at Giant supermarket at Yishun Street 72 when he insulted the modesty of the 26-year-old woman on May 29.

The court heard that Pang had finished his shift that day and learnt that his work would be taken over by the victim, a sales team leader.

He knew who she was and was curious to know what she would look like without her clothes on, said Deputy Public Prosecutor Terence Szetoh Khai Hoe.

Pang decided to take a video of her changing into her staff uniform.

At about 11pm, he went into the staff toilet cubicle. After setting his mobile phone into video recording mode, he placed it on a shelf in the toilet with the camera pointing towards the middle of the toilet.

He left. A few minutes later, the victim entered the toilet to change and was caught on video without her top on and in her bra, She suddenly saw the cellphone on the shelf and stopped the video recording.

As she recognised that the phone belonged to Pang, she immediately confronted him. He apologised, and she called the police.

Further investigation showed that the mobile phone had an eight-minute long video recording containing footage of the victim taking off her blouse and exposing her upper body and bra.

Pang has unrelated convictions 10 years ago for burglary, lurking house trespass and outrage of modesty. He could have been jailed for up to one year and/or fined for insulting modesty.
