Report terrorism

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

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.

Protecting Cambridgeshire from terrorism remains one of our main priorities. Our skilled and specialist team works to gather and develop intelligence to protect our communities from terrorism and extremist activity.

Thankfully terrorist activity in Cambridgeshire is rare but we urge you to be alert and aware of your surroundings at all times.

Report online

If you suspect anything unusual, you should report your concerns to us. 

You can also report information or suspicious activity to the MI5. Any information you share will be analysed by specialist officers and treated in confidence. 

Alternatively, you can report confidentially online to or by calling the anti-terrorism hotline.

Report online terrorism or extremist material

If you’ve come across a website or online content (such as emails, images, videos, forums or social media) that you feel is of a violent extremist or terrorist nature, please report it using the GOV.UK anonymous online reporting service.

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.

Report by phone

When reporting an emergency, or the belief of an imminent danger, always call 999. There are other ways to contact us in an emergency if you are hard of hearing or are in a hostile environment and cannot speak.

Alternatively, you can call the anti-terrorism hotline.

Anti-terrorism hotline

The anti-terrorism hotline 0800 789 321 is available 24/7 for members of the public to report suspicious activity. In the event of an emergency, you should always call 999.

Calls are answered by specially trained counter terrorism officers and staff. They will then pass the details over to local counter terrorism officers for further investigation, if appropriate.

The service is confidential and we encourage you to trust your instincts and call if you have any concerns about suspicious activity. 

Report anonymously

We ask everyone who provides information to 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 visit the Crimestoppers website or call them on 0800 555 111.

Reporting confidentiality

We treat all 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.

If you'd prefer not to speak with us, you may wish to contact one of the organisations below in complete confidence. They can pass your information to us and preserve your anonymity.
