The central agencies are controlled by the central Government of India. The majority of federal law enforcement agencies are controlled by the Ministry of Home Affairs. The head of each of the federal law enforcement agencies is always an Indian Police Service (IPS) officer. The constitution assigns responsibility for maintaining law and order to the states and territories, and almost all routine policing—including apprehension of criminals—is carried out by state-level police forces. The constitution also permits the central government to participate in police operations and organisation by authorising the creation of Indian Police Service.
Central police forces can assist the state's police force, but only if so requested by the state governments. In practice, the central government has largely observed these limits. During the Emergency of 1975-77, the constitution was amended (effective 1 February 1976) to permit the central government to dispatch and deploy its Central Armed Police forces without regard to the wishes of the states. This action proved unpopular, and the use of the Central Police Forces was controversial. After the Emergency was lifted, the constitution was amended in December 1978 to make deployment of central Police forces once again dependent on the consent of the state government.
Ministry of Home Affairs
The principal national-level organisation concerned with law enforcement is the Ministry of Home Affairs (MHA), 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 of being the cadre controlling authority of the IPS, the Ministry of Home Affairs maintains several agencies and organisations dealing with police and security. Police in the union territories comes directly under MHA.
The Minister of Home Affairs is the cabinet minister responsible for Ministry of Home Affairs, whereas the Home Secretary, an Indian Administrative Service (IAS) officer, acts as the administrative head of Ministry of Home Affairs.
Central Armed Police Forces
Border Security Force
The Indian Border Security Force (BSF) is responsible for policing India's land borders during peacetime and preventing trans-border crimes. It is a central police force operating under the MHA. It performs a variety of duties ranging from VIP security to election duties, from guarding of vital installations to counter-naxal operations.
The Indo-Pakistani War of 1965 demonstrated the inadequacies of the then existing border management system and led to the formation of the Border Security Force as a unified central armed police force with the specific mandate of guarding India's international boundary with Pakistan. The BSF's policing capabilities were used in the Indo-Pakistani War of 1971 against the Pakistani Armed Forces in areas which were least threatened. During wartime or upon orders from the central government BSF operates under the command of the Indian Army. BSF troops took part in the Battle of Longewala in 1971 in this capacity. After the 1971 war which led to the creation of Bangladesh, the responsibility for policing the border with Bangladesh was also assigned to Border Security Force.
Although originally charged with guarding India's external boundaries, the BSF has more recently been given the task of counter-insurgency and counter-terrorism operations. When the insurgency in Jammu and Kashmir broke out in 1989, the Jammu and Kashmir state police and the thinly-deployed Central Reserve Police Force (CRPF) needed extra force to cope with the spiralling violence, the Indian government deployed the BSF to Jammu and Kashmir to combat Kashmiri militants.
BSF operates a Tear-Smoke Unit situated at BSF Academy at Takenpur, Gwalior in Madhya Pradesh which supplies tear gas and smoke shells for riot prevention to all of the state police forces. BSF operates Dog Squads and runs the National Dog Training and Research Centre. BSF is one of several Indian police forces which has its own Air and Water wings. It provides helicopter, dog and other support services to the state police.
Central Industrial Security Force
The primary task of CISF is providing industrial security. The Central Industrial Security Force (CISF) is used to guard industrial installations around the country owned by the Central government as well as securing seaports and airports. CISF also provides security to certain NGOs. They provide security for atomic power plants, space installations, mints, oil fields and refineries, major ports, heavy engineering plants, steel plants, barrages, fertilizer units, airports, hydroelectric/thermal power plants and other installations partially or wholly run by the government.
Central Reserve Police Force
The Central Reserve Police Force (CRPF) is one of the largest Central Police organisations in the world. Its main objective is to assist and help states and union territories' law enforcement agencies in maintaining law and order and to contain insurgency. It is also deployed as anti-terrorist unit in various regions.
It is even operating abroad as part of United Nations peacekeeping missions. It performs a variety of duties ranging from VIP security to election duties, from guarding of vital installations to the counter-naxal operations.
Indo-Tibetan Border Police
The Indo-Tibetan Border Police (ITBP) is one of the five main Central Armed Police Forces, responsible for security along the Indo-Tibetan Border, covering 2115 km. The ITBP personnel are trained in the fields of law and order, military tactics, jungle warfare, counter insurgency and internal security
ITBP is an elite and agile force with a strength of about 90,000 personnel. It is involved in war-time and peace-time duties at the border and the surrounding areas.
National Security Guards
The National Security Guards (NSG) is a commando unit originally created for counter-terrorism and hostage rescue missions. Raised in 1986, it is popularly known as the "Black Cats" for the uniform worn by its operators. Like most military and elite security units in India, it is media-shy and the general Indian public is largely unaware of its capabilities and operational details.
The NSG draws its core members from the Indian Army and the balance support staff from various central police units. It is India's premier counter-terror outfit and is typically deployed in situations that would be beyond the capabilities of regular police units. An NSG team with a dedicated transport aircraft is always stationed at Palam airport in New Delhi, ready to deploy in 30 minutes. The NSG has also been increasingly tasked with protection of VIPs. This role has expanded in recent years, as several politicians have come to view NSG protection as a status symbol. This has caused some concern among senior NSG officers and Home Ministry officials.
Special Protection Group
The Special Protection Group (SPG) is the executive protection agency of the Government of India. It is responsible for the protection of the Prime Minister of India, and his/her immediate families. The force was established in 1985 after the assassination of Indira Gandhi. It provides the security 24 by 7 all over India to Prime Minister including ex prime Ministers and their Family Members at any location across India.
Sashastra Seema Bal (SSB)
The Sashastra Seema Bal, formed in the year 1963, is one of the five main Central Armed Police Forces, deployed at the Indo-Nepal and Indo-Bhutan borders. SSB is a dedicated Central Armed Police Force having more than 82,000 personnel. The SSB personnel are trained in the fields of law and order, military tactics, jungle warfare, counter insurgency and internal security. SSB personnel also serve in the Intelligence Bureau (IB), Research and Analysis Wing (R&AW), Special Protection Group (SPG), National Security Guards(NSG) etc. on deputations. The officers start from the level of an assistant commandant (A.C), equivalent to the deputy superintendent of police (Dy.SP) in a state and retire at the rank of inspector general(IG).
Central investigation and intelligence institutions
Central Bureau of Investigation
The Central Bureau of Investigation (CBI) is India's premier investigative agency, responsible for a wide variety of criminal and national security matters. It is often cited to have been established from
The Delhi Special Police Establishment Act, 1946. However it must be noted that it was formed not by the Delhi state government but by the Central Government (Home Ministry) which controls the police in Delhi. The CBI thus, was formed by a mere resolution by the Central government than by legislation. This led to a case whereby the constitutionality of this government agency was questioned in the Narendra Kumar vs Union of India case in the High Court of Gauhati, Assam because the matter of all areas of policing (arrests, searches, etc.) is exclusive to state governments whereas the CBI was formed by the Central government with all the areas of policing when such powers regarding policing, are not given to the Central Government. The Gauhati High Court ruled that despite the lack of legislation, the CBI is a formal and authorized agency of the Central government to carry out policing all across the nation. The case was appealed to The Supreme Court of India which also stayed the High Court order in light of the fact that not only does India need a Central Police Force for policing for better integration in law and order but also the fact that the CBI had helped to carry out several pending cases and led to successes in investigations regarding infamous events such as the Anti-Sikh riots, the 2G spectrum scam, etc.
The Central Bureau of Investigation is controlled by the Department of Personnel and Training in the Ministry of Personnel, Public Grievances and Pensions of the Government of India usually headed by the prime minister as the Minister of Personnel, Public Grievances and Pensions. It is India's official Interpol unit. The CBI draws its officers from the IPS and IRS officers around the country. It is responsible for investigation into various crimes and national security matters. The agency specializes in investigating crimes involving high ranking government officials and politicians and in some instances, criminal cases that don't necessarily involve politicians or high-ranking officials, have been referred to the agency for investigation because of media and public pressure because of incompetency from the local police investigations.
