The State Police Force's higher-ranking officials are known as Deputy Superintendents of Police. They have the same authority as the Assistant Chief of Police (ACP). They are recognised or posted as Circle Officers in numerous states, such as Rajasthan and Uttar Pradesh (C.O.). A DSP, also known as a Sub-divisional Police Officer or SPDO, is the officer in command of a subdivision in West Bengal. These officers report to the Superintendent of Police and are superior than assistant superintendent officers. The DSP is the police force post in the commonwealth and is utilised in numerous countries founded by the British Empire (such as India and Singapore).
