You can help us prevent terrorism and save lives. Even if you’re not sure, please let us know so our specially trained officers can look into it, no call or click will be ignored. Remember - Action Counters Terrorism.

How do I report possible terrorist activity?

There are different ways you can tell us about possible terrorist activity either in the UK, or that might affect the UK.

Report it online using our quick and confidential online tool, or call the confidential Anti-Terrorism Hotline on 0800 789 321. We monitor this service 24 hours a day.

If it’s an emergency and you suspect an immediate danger call 999.

How do I report online terrorist or extremist content?

If you’ve come across a website or online content (including emails, forums or social media) that you feel is of a violent extremist or terrorist nature, please report it using the UK Government’s quick and anonymous online tool.

Specialist officers will assess your information and, where appropriate, investigate the website and work with partners to remove it.

Of course, if you suspect an immediate danger please call 999 now.

Can anyone find out that I contacted the police?

Not if you don’t want them to. We treat all of the information that you provide in the strictest of confidence. If we do need to get in touch for any reason we will be extremely discreet.

Can I remain anonymous?

We ask everyone providing information to also give their name and contact details but this is your decision. By providing your contact details this will help us verify the authenticity of the information and support you as quickly as possible if we need to.

If you’d prefer to give information anonymously, please call Crimestoppers on 0800 555 111.

What if the information I give is wrong?

That’s okay. If you have a genuine concern about something you’ve seen or heard, we’d much rather you tell us than keep it to yourself. That way, our specially trained officers can look into it. If it turns out to be nothing, that’s good news.
