History

Ever since the enactment of Act V of 1861, whereby the police system of British India got streamlined, there were proposals at regular intervals to form a specialised detective wing. However it was not till the Police Commission of 1902-03, which finally recommended the formation of a Criminal Investigation Department for each of the provinces that the concept was seriously examined. It was recommended that a Criminal Investigation Department (CID) should be constituted in each province under a Deputy Inspector General of Police for the purpose of collating and distributing information regarding organised crimes. It would also be in charge of Railway Police and the Finger Print Bureau, which was earlier under the Secretariat Police Officer. The CID would also undertake the investigation of specialised crimes that require technical expertise. Finally on 21 March 1905 the Government of India accepted the proposal of the Commission and issued instructions to start the department in every province by 1907. In Bengal the CID came into existence on 1 April 1906 under Mr. C.W.C. Plowden.

Organisation

CID is headed by an Additional Inspector General of Police who is a member of Bangladesh police. Like other branches of police it has senior officers like Deputy Inspector Generals, Additional Deputy Inspector Generals, Superintendents, Additional Superintendents, assistant Superintendents, Inspectors, Sub Inspectors and the constabulary. Officers attached to this wing generally add the prefix 'Special' before their regular rank.
