The Criminal Investigation Department (CID) is the branch of all Territorial police forces within the British Police and many other Commonwealth police forces, to which plain clothes detectives belong.
Contrary to practice in police forces of many other nations, detectives are not automatically senior to uniformed officers and hold the same ranks. The head of the CID in most police forces is a Detective Chief Superintendent.
These ranks are common to most forces.
- Detective Constable (DC)
- Detective Sergeant (DS)
- Detective Inspector (DI)
- Detective Chief Inspector (DCI)
- Detective Superintendent (DSupt)
- Detective Chief Superintendent (DCS)
