When turn-ons lead to trouble


Sean Chew Jun Yang, 26, derived sexual gratification from thinking about boys defecating and watching the images sent to him by his victims.

Under the guise of doing an experiment for a school project, the final-year chemical engineering polytechnic student drugged 13 boys over a period of three years.

Even while on bail after his arrest in June 2012, Chew continued to poison boys with large amounts of laxatives.

He did this because he wanted to watch his 12- to 14-year-old victims vomiting and having diarrhoea. He told them to send him photographs or video clips.

On Nov 13 this year, Chew was sentenced to a total of 36 months' jail for causing hurt and trying to cause hurt by poison.

He is out on $20,000 bail.


In 2011, a 31-year-old sales representative, who claimed to have fantasies about eating children's faeces, admitted to trespassing.

He had entered two kindergartens, defaced the walls of a toilet and written obscene messages on a whiteboard in a classroom.

In one instance, he went into a childcare centre, found several soiled diapers in a toilet and wanted to use them while masturbating.

Instead, he took the diapers and smeared the contents on the centre's walls.

The man was arrested and sentenced to six months' jail and fined $2,500.


In 2013, a serial thief with a fetish for sniffing women's leather wallets was jailed 13 months.

The 48-year-old man claimed he was sexually aroused by the smell of leather.

He would also take upskirt pictures. Since 1986, he had been in and out of court - spending a total of 16 years behind bars.

He was spared a jail sentence in May 2011 and placed on probation due to his psychiatric disorder.

But he breached the order by stealing again and insulting a woman's modesty.

He was subsequently sent to jail.


In 2011, a 48-year-old, who derived sexual pleasure from riding motorbikes belonging to others, was caught stealing an $8,700 bike at Marina Bay Sands.

He had been diagnosed with the fetish more than 20 years earlier, and it had landed him in jail at least three times.

A psychiatrist found that he was suffering from depression and paraphilia, a condition characterised by abnormal sexual desires involving dangerous activities.
