Singapore authorities have arrested three teenagers in separate extremist-related cases, with the most serious allegations involving an anti-LGBTQ+ plot. Security officials said two male teens are accused of planning knife attacks aimed at LGBTQ+ students, raising fresh concern about youth radicalisation in the city-state.

According to the information released so far, the two teenagers allegedly became radicalised online before moving toward plans for violence. The case has drawn attention because it combines online extremism with a targeted threat against LGBTQ+ people, especially students who were reportedly identified as intended victims.

Authorities also detained a third teenager in a different case linked to suspected extremist activity. Few details were immediately available about that separate investigation, but the arrests together suggest Singapore is dealing with multiple youth extremism cases at once.

The developments highlight how online spaces can play a role in pushing young people toward violent ideology. Singapore's latest teen arrests over an alleged anti-LGBTQ+ extremist plot are likely to intensify scrutiny of online radicalisation and threats aimed at minority communities.
