Specifically – the 18-year-old was getting a blowjob from his 16-year-old girlfriend at a staircase.
Little did he know that a police officer had been tailing him, and caught him in the act.
But this cop – dressed in his Jurong Police Division polo T-shirt and blue police trousers while dangling his police warrant card from a lanyard strung around his neck – exercised his authority in the most shocking way possible.
Mohd Shazwan Sapuwan had took pictures of the sex act, and used them to threaten the couple.
He took down their particulars, saying he wanted to report them for public nudity.
He also demanded that the repeat their sex act so he could film them using his handphone.
Afraid that she would be discovered, the girl convinced her boyfriend to let her perform a blowjob on him again – this time while Shazwan was recording.
While she was doing that, Shazwan groped her breast, and later made her give him a blowjob.
He then asked the boyfriend to have sex with her, but he refused.
Shazwan then raped the girl as her boyfriend watched.
The next day, Shazwan texted the boyfriend and asked him for S$40, which he duly delivered.
The incident, which happened on 24 October 2014, only came to light when the girl broke down in school and confided in her friends.
They persuaded her to make a police report.
It was later discovered that the rogue national service policeman had been extorting money from couples after tailing and recording them performing sex acts in public.
Now 23 years old, Shazwan has been jailed for 18 years and will receive 15 strokes of the cane, after pleading guilty to rape, oral sex, outrage of modesty and extortion.
