Criminal Investigation Department (Ireland)

The Criminal Investigation Department (CID) in the Irish Free State was an armed, plain-clothed counter-insurgency police unit that operated during the Irish Civil War. It was organised separately from the unarmed Civic Guard police force. The unit was formed shortly after the truce with the British (11 July 1921)^[1] and disbanded in October 1923.
