Court Verdict and Sentencing
On 18 June 2024, Chew Jun Yang, 36, received a term of six years and one month in prison after pleading guilty to 11 offences involving sexual exploitation of teenage boys. The convictions covered cheating by personation, sexual communication for sexual gratification, causing hurt by an unwholesome drug, and deceiving a person into creating intimate recordings. An additional 17 charges were taken into account when the court determined the sentence.
Modus Operandi and Victim Targeting
From 2018 to 2023 Chew used WhatsApp to impersonate primary-school classmates, claiming to conduct surveys or scientific experiments. He solicited personal details, photographs, voice recordings and videos of boys describing or acting out diarrhoea and stomach cramps. He sometimes mailed substances—cooking oil, baking soda, prune juice or laxatives—to induce diarrhoea, directing victims to record the episodes via video calls. He also joined an online gaming chat group to gain trust.

Official Statements & Responses
The prosecution argued that Chew’s fetishistic disorder was “not mitigating” and emphasized his awareness of the legal and moral wrongfulness of his actions. The court noted his prior conviction and continued reoffending while on bail as aggravating factors influencing the sentence.
Criticism & Opposition
Legal commentators expressed concern that the offender’s mental-health claim did not reduce culpability, highlighting the need for stronger safeguards against online exploitation of minors.
On-the-Ground Reports
One victim recounted being instructed to ingest cooking oil and baking soda during a video call, to document diarrhoea symptoms, and later confronting Chew after recognizing the impersonated friend. Another described a two-hour call in which he was repeatedly urged to use the toilet after drinking prune juice, without success.
Conflicting Reports & Gaps
- The exact number of victims remains uncertain; sources cite “at least 30” contacts but do not confirm a total count.
- The composition of the “unknown substances” delivered in 2019 is not fully detailed beyond references to cooking oil, baking soda, prune juice and a laxative.
- The IMH report is dated July 2025, later than the court proceedings, leaving the timing of the clinical assessment unclear.
What’s Next
Chew will serve his sentence in a Singapore correctional facility. The case may prompt further review of online child-exploitation monitoring and the handling of fetish-related mental-health claims in criminal proceedings.
