The
National Investigation Agency (
NIA) is the primary counter-terrorist task force of India. The agency is empowered to deal with the investigation of terror related crimes across states without special permission from the states under written proclamation from the Ministry of Home Affairs. The Agency came into existence with the enactment of the National Investigation Agency Act 2008 by the Parliament of India on 31 December 2008, which was passed after the deadly 26/11 terror attack in Mumbai. Such an attack revealed the failure of intelligence and ability to track such activities by existing agencies in India, hence the government of India realized the need of a specific body to deal with terror related activities in India, thereby establishing the NIA. Headquartered in New Delhi, the NIA has branches in Hyderabad, Guwahati, Kochi, Lucknow, Mumbai, Kolkata, Raipur, Jammu, Chandigarh, Ranchi, Chennai and Imphal. It maintains the NIA Most Wanted list.
