The origin of the Kolkata (Calcutta) Police dates from the landing of Job Charnock in Sutanati, the embryo of the metropolis, on 24th August 1690. The modern Police Force in India begins from the appointment of a Commissioner of Police in Calcutta on 1st November 1856. The Commissionerate system of Policing is thus the contribution of Calcutta to India. The Kolkata Police is yet to conclude its year-long 150th anniversary celebration in November 2006. The evolution of the Calcutta Police has not yet been documented; so is also the history of Lalbazar, its headquarters.
