Radicalisation is when someone starts to believe or support extreme views, and in some cases, then participates in terrorist groups or acts.
It can be motivated by a range of factors, including ideologies, religious beliefs, political beliefs and prejudices against particular groups of people. There is no obvious profile of a person likely to become radicalised and involved in extremism. The process of radicalisation is different for every individual and can happen in many different ways, and over different time frames from as little as a few days or hours, or it may take several years.
It can be hard to know what to do if you’re worried someone close is expressing extreme views or hatred, which could lead to them harming themselves or others.
If you have any concerns that someone may be being influenced by others get help - talk to someone you can trust.
If there is an immediate threat of harm to others or information on imminent travel contact the Police 999 or Anti-Terrorist Hotline 0800 789 321. You can remain anonymous, and you may save lives.
