Deputy Superintendent of Police !

The rank of deputy superintendent of police or Assistant commissioner of police (ACP), in the commissionerate system,[1] was created in 1876 as the policy of Indianisation was introduced. It was originally a rank only held by Indians and was equivalent to assistant superintendent (a rank then only held by Europeans). Deputy superintendents (DSP or DySP) are now state police officers who belong to the provincial police forces, either direct entrants at that rank or promoted from inspector. Assistant commissioners of police, who are members of the provincial forces, can be promoted to the Indian Police Service after limited years of service which varies from 8 to 15 years depending on the state.[2] Deputy superintendents are generally posted as circle officers in a district. In the states of Rajasthan and Uttar Pradesh, the rank is commonly known as circle officer (CO), although this is not technically correct as CO is a post, not a rank. In the state of West Bengal, a DSP is in charge of a sub-division and is most commonly known as a sub divisional police officer (SDPO).
