If you have any information on any threat to Singapore’s security, such as a suspected case of radicalisation, terrorism, communal extremism or foreign interference, please contact ISD at 1800-2626-473 (1800-2626-ISD) or
You can also contact the Singapore Police Force at 999, if it is an emergency.
The terrorism threat has shown that security agencies alone cannot detect every radicalised individual in Singapore. The community plays an important role. Family, friends and colleagues are best placed to notice changes in an individual.
The time between radicalisation and commission of violence can be very short in some cases. Early reporting allows the authorities to investigate and intervene early to stem the radicalisation, before the individual harms or kills someone. Reporting to the authorities can save these individuals from themselves.
