India’s first ever dedicated Detective Department was set up in 1868 by then Commissioner of Police Sir Stuart Hogg, primarily to control the incidence of major crime in the city, and its detection. Today, it is headed by a Deputy Commissioner, assisted by the Deputy Commissioner DD II. The Detective Department is made up of several squads and sections dealing with specialised types of crime.

Cyber Crime Police Station

In 2010, Kolkata`s first Cyber Crime Police Station was set up in Lalbazar with technical support from Infosys Technologies. The initial idea was to provide the city with knowledge-based policing. But given the steady growth of cyber crime over the next decade and more, the Cyber Crime PS has assumed a far more important role. In 2018, with cyber crimes in the city having registered a drastic increase, dedicated cyber police stations were also set up in each of Kolkata’s nine police divisions.

The Cyber Crime PS is housed within the Detective Department building and complaints can be directly lodged here both offline or via email to dccyber@kolkatapolice.gov.in. The PS is under the supervision of the Joint Commissioner of Police(Crime).
