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. It is thus distinct from the Uniformed Branch and the Special Branch.
Contrary to practice of 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.
Attorneys at Law – Justice in Hands
In some police forces some branches generally within the CID environment such as Special Branch and Child Protection are not always staffed with qualified detectives. This is a reflection of the highly specialised nature of their work which does always not call for an “all round detective” background but instead requires officers with exceptionally detailed specialist knowledge. Some forces appoint such non-detective officers to ‘Branch Detective’ status, allowing them to use the ‘Detective’ prefix.
This has had a knock on effect with fewer and fewer officers opting to train as detectives.
