The principal national-level organization concerned with law enforcement is the Ministry of Home Affairs, which supervises a large number of government functions and agencies operated and administered by the central government. The ministry is concerned with all matters pertaining to the maintenance of public peace and order, the staffing and administration of the public services, the delineation of internal boundaries, and the administration of union territories.
In addition to managing the Indian Police Service, the Ministry of Home Affairs maintains several agencies and organizations dealing with police and security. Police in the union territories are the responsibility of the Police Division, which also runs the National Police Academy and the Institute of Criminology and Forensic Science. The Central Bureau of Investigation investigates crimes that might involve public officials or have ramifications for several states. The ministry also is the parent organization of the Border Security Force.
