Counter Terrorism Command

The Counter Terrorism Command (CTC) – also known as ‘SO15’ – is based within the Metropolitan Police Service and is responsible for leading Counter Terrorism-related investigations in the whole London area, as well as Prevent work across London’s boroughs to help to stop those vulnerable to radicalisation from being drawn into terrorism.

The CTC is also responsible for supporting the Eastern Region Special Operations Unit (ERSOU) with investigations and provides investigative and operational support to forces across the Eastern region as required.

In addition to this, the CTC also hosts a number of national and international functions on behalf of Counter Terrorism Policing. This includes the War Crimes Team, the National Terrorist Financial Investigation Unit, the Counter Terrorism Internet Referral Unit, which is part of the National Digital Exploitation Service hosted within the CTC.

The CTC also hosts Counter Terrorism Policing’s International Operations team, including a network of around 40 Counter Terrorism Police Liaison Officers who are deployed in various locations around the world and work to assist our efforts to tackle terrorism and extremism globally.
