National Investigation Agency (NIA)

Definition

India's central counter-terrorism law-enforcement agency, set up under the National Investigation Agency Act, 2008, to investigate and prosecute offences affecting national security.

Key points

• Created in the aftermath of the 26 November 2008 Mumbai attacks; it functions under the Ministry of Home Affairs.
• It can investigate scheduled offences, including terrorism, across States without prior permission from the State concerned, which is an exception to the usual federal arrangement of law and order being a State subject.
• The 2019 amendment widened its jurisdiction to offences such as human trafficking, cyber-terrorism, and certain offences committed by Indians abroad.
• Cases are tried in designated NIA Special Courts, and the agency often works with anti-terror laws such as the UAPA.
• It maintains a national database and coordinates with State police and central agencies on terror investigations.

Why it matters for CAPF

The NIA is the apex counter-terror investigation body, a clear institutional fact for internal security and an example of the Centre's role in security despite police being a State subject.

Common confusion

The NIA investigates and prosecutes terror cases; do not confuse it with intelligence agencies (the Intelligence Bureau for internal intelligence, the Research and Analysis Wing for external), which gather intelligence rather than prosecute.
