Singapore detains 3 youths under security law, 1 planned to attack teachers, schoolmates
Authorities said the youths were self-radicalized online and had prepared knife, bomb and cyberattack plans before their arrests.
- On Monday, July 27, 2026, Singapore's Internal Security Department announced the detention of three male youths aged 14, 15, and 19 under the Internal Security Act for plotting separate attacks on schools and a military airbase.
- All three youths were self-radicalized online by violent extremist ideologies and developed attack plans while detained between April and June 2026, according to the ISD. Investigators noted the teens were at varying stages of preparation when arrested.
- Drafting a 21-page manifesto titled "A Call to Action," a 14-year-old student planned a mass stabbing attack at his school during June holidays. Authorities described the arrest as a "close shave" after a peer noticed radicalization signs and alerted officials in May.
- Coordinating Minister for National Security K. Shanmugam and Education Minister Desmond Lee emphasized schools must remain open spaces and urged community vigilance. The ISD will focus on rehabilitation while the Ministry of Education supports the detainees' continued studies during detention.
- The ISD identified the 14-year-old's case as the first detention involving "composite violent extremism" , where individuals subscribe to multiple conflicting ideologies. Officials warned youth radicalization remains a persistent threat fueled by easy online access to extremist material.
