The Criminal Investigation Department (CID) is the branch of a police force to which most plainclothes detectives belong in the United Kingdom and many Commonwealth nations. A force's CID is distinct from its Special Branch. The name derives from the CID of the Metropolitan Police, formed on 8 April 1878 by C. E. Howard Vincent as a re-formation of its Detective Branch. British colonial police forces all over the world adopted the terminology developed in the UK in the 19th and early 20th centuries, and later the police forces of those countries often retained it after independence. English-language media often use "CID" as a translation to refer to comparable organisations in other countries.
Special police usually describes a police force or unit within a police force whose duties and responsibilities are significantly different from other forces in the same country or from other police in the same force, although there is no consistent international definition. A special constable, in most cases, is not a member of a special police force (SPF); in countries in the Commonwealth of Nations and often elsewhere, a special constable is a voluntary or part-time member of a national or local police force or a person involved in law enforcement who is not a police officer but has some of the powers of a police officer.
