National Investigation Agency

The need for setting up of an Agency at the Central level for investigation of offences related to terrorism and certain other Acts was felt long back.Several experts and Committees, including the Administrative Reforms commission in its Report, had made recommendations for establishing such an Agency.

The Government after due consideration and examination of the issues involved, proposed to enact a legislation to make provisions for establishment of a National Investigation Agency in a concurrent jurisdiction framework, with provisions for taking up specific cases under specific Acts for investigation.

Accordingly the NIA Act was enacted on 31st August 2008 which gave birth to National Investigation Agency (NIA). At present NIA is functioning as the Central Counter Terrorism Law Enforcement Agency in India.

NIA has registered and investigated 244 cases till date. After submission of charge sheets, 37 cases have been finally or partially decided in trial. Of these, 35 cases have ended in conviction giving NIA an enviable conviction percentage of 91.3%.
