The Malabar Special Police (MSP) is an armed police battalion of the State Police of Kerala, India. MSP is headquartered in Malappuram, Kerala. The unit also trains new recruits and also helps the local police to maintain law and order during emergencies. During emergencies, this unit forms the riot police platoons fully equipped with riot gear. This police unit is known for its extraordinarily tough training, and the high quality of its firing and military drills. The MSP, initially known as Malappuram Special Police, originated in 1884 as a paramilitary unit tasked with managing the Malabar rebellion under British rule. Richard Hitchcock, the district superintendent of police for South Malabar at that time, advocated for the creation of this battalion, modeled after an Indian Infantry battalion.
