Crime Branch CID
The Crime Branch CID, a specialist unit headed by an officer of the rank of Additional Director General of Police and assisted by an IGP and two DIGs, is responsible for the investigation of especially complicated cases, heinous crimes or sensational cases. It also investigates communal riot cases and cases involving counterfeit currency and passports/visas. The concept of the Crime Branch was conceived in view of the fact that the district police are overburdened with a host of duties and thus cannot devote as much time and apply as much professional expertise to the investigation of such cases as they deserve.
The selection of the cases to be entrusted to the CBCID is made generally by the DGP (or the CBCID itself), the state government or the High Court. Investigations by the CBCID are characterized by thorough and sustained investigation involving the latest scientific techniques.
It has got seven territorial and three other special units, each headed by a Superintendent of Police. On an average, the CBCID investigates about 450 cases per year.
