About CID

Criminal Investigation Department (CID) is one of the ancient and specialized units of Bangladesh Police. It is the apex body of investigation of Bangladesh Police as well as Bangladesh government. Investigation of scheduled cases suggested by laws and cases instructed from courts is the basic function of CID. CID also undertakes the investigation of specialized crimes that require technical expertise. Apart from investigation there are some special functions too, through which CID assists other organs of the Bangladesh government through providing expert opinion in various cases.

History Of CID

CID has its own century old history and heritage. During the British regime in 1902-1903, a commission was formed by Lord Curzon for making recommendations to reshape the organizational and functional structure of police. According to the recommendations the colonial police was further organized. One of the recommendations was to constitute Criminal Investigation Department (CID) in each province under a Deputy Inspector General as the administrative head. Eventually on March 21, 1905 the then British India Government accepted the recommendation of the Commission and ordered to start the department in every province by 1907. In Bengal the CID came into existence on April 01, 1906 with Head Quarter’s in Calcutta. Later East Pakistan CID started functioning with Head Quarter’s in Dhaka in 1947. Following the liberation in 1971, CID Bangladesh commenced its journey. In the year 1991, the post of DIG as head of CID has been promoted to Addl. IGP.
