CuriousCats Full Story

Three Singaporean teens, aged 14 to 19, were detained under the Internal Security Act for planning violent extremist attacks inspired by ISIS. The Internal Security Department (ISD) revealed that one teen, a Secondary 2 student, idolised mass shooters and aimed to carry out a mass stabbing at his school during the June holidays.1

The 14-year-old had created a detailed manifesto and was influenced by online violent content and experiences of bullying. Meanwhile, the other two teens targeted Singapore Armed Forces (SAF) personnel and LGBTQ students, with intentions to use bombs in their attacks.23

ISD emphasized that the three youths showed a strong resolve to enact violence and were at various stages of their attack plans when arrested. They stated, 'These three cases drive home the severity of the youth radicalisation threat in Singapore.'5

In the past decade, more than half of the 23 youths dealt with under the ISA had intended to mount attacks in Singapore, highlighting a concerning trend. In response, the Ministry of Home Affairs (MHA) announced on July 27 that police have issued disabling directions against an online service provider and two access-blocking directions to internet service providers to combat terrorism-related content accessible in Singapore.6
