Counter Terrorism Internet Referral Unit (CTIRU)


The ACPO Counter Terrorism Internet Referral Unit (CTIRU) was set up in a bid to make the internet a more hostile place for terrorists.

The CTIRU aims to remove unlawful terrorist material content from the internet with a focus on UK based material. The unit also works with international partners to remove material hosted abroad.

The unit provides the police service with a pool of experts who carry out initial assessments of terrorist and violent extremist material on the internet.

It is also responsible for alerting forces, Counter Terrorism Units/Counter Terrorism Intelligence Units and the Metropolitan Police Service Counter Terrorism Command to online terrorist offences that may fall within their jurisdiction.

The CTIRU also has a national responsibility for serving any Section 3 Terrorism Act notices within the UK and focuses on developing and maintaining relationships with the internet industry and also forging links with key international partners.

The internet is used by some people to promote terrorism and violent extremism and corrupt individuals who are vulnerable to radicalisation. 


Some examples of illegal terrorist or extremist content include:
• speeches or essays calling for racial or religious violence
• videos of violence with messages of ‘glorification’ or praise for the attackers
• chat forums with postings calling for people to commit acts of terrorism or violent extremism
• messages intended to stir up hatred against any religious or ethnic group
• bomb-making instructions
