If you’ve seen or heard something that could suggest a terrorist threat to the UK, even if it seems minor or not worth mentioning, trust your instincts and ACT (Action Counters Terrorism) by reporting it. Any piece of information could be important, it's better to be safe and report. Your information could save a life. Below you’ll find all the different ways you can report possible terrorist activity, as well as answers to our most commonly asked questions.

How do I report possible terrorist activity?

If you're suspicious of something that could identify a terrorist threat anywhere in the UK, report it using our quick and confidential online tool to report possible terrorist activity, or call the Anti-Terrorism Hotline on 0800 789 321.

Even if you’re not sure or it seems trivial, please let us know so that our specially trained officers can look into it, no call or online report will be ignored. The hotline is staffed 24/7.

A textphone service is available for people with speech or hearing difficulties on 0800 0324539 (text messages from mobiles are not accepted).

Of course, if you suspect an immediate danger, whether it’s suspicious behaviour, a package or a vehicle, move away and call 999 now. If you have a hearing or speech impairment, use our textphone service 18000 or text us on 999 if you’ve pre-registered with the emergencySMS service.

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 to report extremist online material.

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 OK. 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.

Can I speak to someone other than the police?

Absolutely. You can speak to the organisations below in complete confidence. They can pass your information to us and preserve your anonymity.
