Internal Security Department

The Internal Security Department (ISD) is Singapore's domestic intelligence agency responsible for national security. Recent events have brought the ISD into sharp focus due to a concerning rise in youth radicalization. In a three-month period this year, the ISD detained three teenagers who had become "self-radicalised" online, adopting violent extremist ideologies. These individuals were planning separate attacks, including shooting, stabbing, and bomb plots. The speed at which these youths were radicalized has reportedly doubled, raising alarms about the effectiveness of current security measures and the pervasive influence of online extremism. The ISD's actions highlight the ongoing threat of radicalization within Singapore and underscore the department's critical role in identifying and neutralizing such threats to maintain national security.
