What should I do if I'm worried my child is being radicalised?

You can get confidential, non-judgemental advice from Act Early (actearly.uk), the safeguarding website run by Counter Terrorism Policing, or call their advice line on 0800 011 3764. Sharing a worry does not mean a child is in trouble; the aim is early support. For an immediate threat to safety, call 999.

What are some signs of online radicalisation in young people?

Possible signs include sudden strong us-versus-them views, secrecy about online activity, new online "friends" who encourage isolation, scripted opinions, or growing intolerance towards others. None alone proves anything, as many are normal teenage changes. Trust your instincts, keep talking, and seek advice from Act Early or your child's school if concerns build.
