Counter Terrorism Command

The Counter Terrorism Command (CTC) or SO15 is a Specialist Operations branch within London's Metropolitan Police Service and the City of London Police. The CTC was established as a result of the merging of the Anti-Terrorist Branch (SO13) and Special Branch (SO12) in October 2006, bringing together intelligence, operations, and investigative functions to form a single command. The CTC has more than 1,500 police officers and staff, including a number of investigators based overseas, and also hosts the Counter Terrorism Policing headquarters.
