Radicalisation and extremism

Radicalisation is the process by which a person comes to support terrorism and extremist ideologies. This powerful video illustrates the impact radicalisation can have on families when someone they love is radicalised. 

Report your concerns

If you are concerned about someone’s activities or behaviour, you can call the Anti-Terrorism Hotline on 0800 789 321 (it is available 24 hours a day, seven days a week).

If you have seen a person acting suspiciously, or if you see a vehicle, unattended package or bag which might be a threat, immediately move away and call 999.

You can report illegal or harmful information, pictures or videos you have found on the internet anonymously to the Home Office.

If you are concerned about someone becoming radicalised in your community, please contact the local police by dialling 101 and ask for the PREVENT team.
