National Investigation Agency (NIA)

On the night of 26 November 2008, ten gunmen attacked Mumbai. The investigation spread across states and borders. Police is a State subject, so many agencies had a hand in it. Parliament asked a hard question afterwards. Should India have one federal agency just for terror cases? Within weeks, it said yes. That agency is the National Investigation Agency, or NIA.

1What Is the NIA and Why Was It Created?

• Think back to 26/11. Mumbai police, state agencies and central agencies all worked on the case. There was no single agency built for terror cases that cross state lines.
• Parliament passed the National Investigation Agency Act, 2008 in December that year. The Act created the NIA.
• The NIA works under the Ministry of Home Affairs. Its headquarters is in New Delhi.
• Radha Vinod Raju, an IPS officer, was appointed its first Director General in January 2009.
• Its job is simple to state. It investigates and prosecutes serious terror and national-security offences anywhere in India.
• Some of its best-known cases include the 2016 Pathankot attack. In April 2025, it also arrested Tahawwur Rana, an accused in the 26/11 plot, after his extradition to India.

2Which Cases Can the NIA Take Up?

• The NIA is not a general crime agency. A local theft or a street fight is never its case.
• It can take up only Scheduled Offences. These are crimes listed in the Schedule to the NIA Act.
• The original Schedule covered offences under the Unlawful Activities (Prevention) Act, 1967, or UAPA.
• It also covered the Atomic Energy Act, the Anti-Hijacking Act and the law on safety of maritime navigation.
• The list is short on purpose. It keeps the agency focused on serious national-security crimes.
• The UAPA was itself strengthened in 2019. Since then, the Centre can designate an individual as a terrorist, not only an organisation.

3How Does a Case Reach the NIA Without State Consent?

• Picture a blast in one State, with links to another State. Waiting for each State to agree would waste precious days.
• The Act solves this in Section 6. A State government that learns of a Scheduled Offence sends a report to the Centre.
• The Centre then decides if the case fits the Act. If it does, it directs the NIA to take over.
• The Centre can also act on its own, suo motu, without waiting for a State request.
• Once the NIA takes over, the State police must hand the case papers to it.
• So the State’s consent is never a condition. This is the single most tested point about the NIA.

4Which Courts Try NIA Cases?

• Terror trials are tense and long. Witnesses may face threats. Ordinary courts may be too busy.
• The Act allows Special Courts for NIA cases. These are Sessions Courts designated for the job.
• The Centre can designate them under Section 11. State governments can do so under Section 22.
• A State can have more than one Special Court. A judge who handles such cases often becomes familiar with them.
• Specialised courts help trials move faster. They can also protect witnesses better.

5Who Leads the NIA?

• A Director General heads the NIA. The post goes to a senior IPS officer of DGP rank.
• In January 2026, the Appointments Committee of the Cabinet named Rakesh Aggarwal as the DG. He is a 1994-batch IPS officer of the Himachal Pradesh cadre.
• His tenure runs up to 31 August 2028. Before him, Sadanand Date held the post.
• A career police officer in charge brings real investigation experience to the agency.
• In July 2024, India’s new criminal laws came into force. The Bharatiya Nyaya Sanhita, or BNS, replaced the Indian Penal Code.
• So the NIA now registers cases under the BNS. It uses the UAPA and other Scheduled laws alongside it.

6What Changed in 2019?

• By 2019, threats had changed. Cyber attacks and human trafficking had grown, but the old Schedule did not cover them well.
• The NIA (Amendment) Act, 2019 added new offences. These included human trafficking, counterfeit currency, manufacture and sale of prohibited arms, cyber-terrorism and offences under the Explosive Substances Act.
• It also gave the NIA extraterritorial reach. The agency can now investigate a Scheduled Offence committed outside India.
• This applies when Indian citizens or Indian interests are involved.
• For such cases, a Special Court in New Delhi has jurisdiction.
• In short, India can now chase terror that targets its people even beyond its borders.

7What Is in the News?

• Manipur’s ethnic violence of 2023 produced many cases. The NIA was given 30 of them.
• It has filed chargesheets in 15 of those cases. The other 15 are still under investigation.
• On 10 August 2026, the Supreme Court asked authorities to consider two exclusive courts. One would hear the CBI cases and the other the NIA cases from the Manipur violence.
• The aim is faster trials, with victims able to track the cases.
