Online Youth Radicalisation
Singapore Authorities Detain Three Youths, Including 14-Year-Old, Under ISA for Online Radicalisation
Anonymous
Key Points
1
The 15-year-old briefly considered travelling to Gaza in 2024 to join Hamas after being exposed to ISIS/Hamas content online, including researching travel routes before deciding against it.
2
The 14-year-old drafted a 21-page manifesto detailing a mass-casualty attack at his secondary school, specifying weapons and targets (including non-Muslim teachers and students) and planning to livestream the assault before taking his own life.
3
The 19-year-old Tan Jun Jie plotted knife attacks on Singapore Armed Forces personnel at Sembawang Air Base and LGBTQ students, and also attempted DDoS cyberattacks against websites of Muslim organisations deemed deviant.

Radicalisation across the cases largely occurred online, with the 14-year-old also exposed to Roblox-based simulations of real-life shootings that fed his violent intents.

These detentions marked the first ISA case involving Composite Violent Extremism (CoVE), a framework that bundles multiple extremist ideologies, previously referred to as 'salad bar' extremism.
Singapore has detained three self-radicalised youths — aged 14, 15, and 19 — under the Internal Security Act (ISA) for plotting separate attacks on schools and military sites, authorities announced on July 27, according to Free Malaysia Today. All three were close to carrying out attacks when they were arrested.
The cases mark the first ISA detentions involving Composite Violent Extremism, or CoVE — a framework covering people who blend multiple extremist ideologies together, The Edge Malaysia reported. Authorities said all three radicalised themselves online.
14-Year-Old Wrote 21-Page School Attack Manifesto
The youngest detainee, 14, is the first person held under the new CoVE framework. He drafted a 21-page manifesto detailing a mass-casualty stabbing at his secondary school, according to Head Topics. He named specific targets, including non-Muslim teachers and students, and listed the weapons he planned to use.
His plan included livestreaming the attack before taking his own life. Authorities also found that he had used Roblox — an online gaming platform — to simulate real-life shootings, which fed his violent intent, Free Malaysia Today reported. He was at an advanced stage of planning before his arrest.
15-Year-Old Dreamed of a Violent Malaya Caliphate
The 15-year-old was inspired by ISIS and harboured ambitions tied to establishing a violent Malaya Caliphate, The Edge Malaysia reported. He was exposed to ISIS and Hamas content online and researched travel routes to Gaza in 2024, briefly considering joining Hamas before deciding against it.
Authorities described him as self-radicalised, with his beliefs shaped entirely by extremist material he found online. He had also considered travelling abroad to support violent extremist causes, according to Free Malaysia Today.
19-Year-Old Targeted SAF Personnel and LGBTQ Students
The oldest detainee, Tan Jun Jie, 19, plotted knife attacks on Singapore Armed Forces personnel at Sembawang Air Base and on LGBTQ students, Market Screener reported. He had also attempted distributed denial-of-service, or DDoS, cyberattacks — a method used to flood and crash websites — against Muslim organisations he considered deviant.
His case shows a mix of targets and motives that fits the CoVE pattern — blending religious extremism with other grievances. Authorities said he was close to acting when he was detained.
Singapore Officials Warn Online Radicalisation Is Getting Faster
Senior officials stressed that the internet played a central role in all three cases. Violent content, extremist videos, and even gaming platforms like Roblox were used as entry points, according to Head Topics. The Ministry of Home Affairs and the Internal Security Department made the announcement jointly on July 27.
Officials warned that CoVE — once called 'salad bar' extremism for how it mixes ideologies — is an evolving threat. They called on the public to stay vigilant and report warning signs early, Free Malaysia Today reported.
