Individual terrorists In 2012, NIA with the assistance of
Interpol and
Saudi Intelligence agencies, successfully arrested terrorists namely:
Abu Jundal alias
Abu Hamza (Indian national),
Fasih Mohammad and
Yaseen Bhatkal (
Indian Mujahideen). In 2013, NIA was successful in arresting two senior members of Indian Mujahideen, namely Ahmed Siddibappa Zaraar alias Yasin Bhatkal and Asadullah Akhtar alias Haddi, at the Indo—Nepal border in Bihar on 29 August 2013. These two were instrumental in the commission of several terrorist attacks across the country for the past several years, under the banner of Indian Mujahideen, a proscribed terrorist organisation. On 8 April 2025, a team of NIA agents took custody of
Tahawwur Rana from the
United States Marshals Service, a co-conspirator of the
November 2008 terror attacks in Mumbai, after his plea to stop extradition was rejected by the
Supreme Court of the United States. The plane carrying Rana reached the Palam Air base in New Delhi on 10 April 2025. He was immediately sent to an 18-day NIA custody by a special NIA court in Delhi, and is currently being interrogated for his involvement in the attack as well as face trial for the attack.

Jammu and Kashmir. On 18 January 2019, NIA filed a
chargesheet against 12 people including
Lashkar-e-Taiba terror group chief

Hizbul Mujahideen chief
Syed Salahuddin. This chargesheet was filed after nearly eight months of investigations spanning six states in India during which over 300 witnesses were examined, 950 "incriminating documents" and 600 electronic devices were seized. NIA has also stated that the war against terror in Kashmir is not about terror funding alone, it's about a conspiracy to wage war against India. During the investigation the NIA has arrested people allegedly involved in stone-pelting incidents for the first time including Kashmiri photojournalist

Manipur Police, NIA arrested a 51-year-old man, Seiminlun Gangte, from
Churachandpur, Manipur for
transnational conspiracy by terror outfits in Myanmar and Bangladesh to wage war against the government of India by exploiting the ethnic unrest in Manipur. NIA announced that
the mentioned militant outfits have been providing funds to procure arms, ammunition and other types of terrorist hardware, which are being sourced both from across the border, as well as from other terrorist outfits active in northeastern states of India. On 17th March 2026, in
Kolkata, the NIA arrested
Matthew Aaron Van Dyke, an
American mercenary and
spy, as an accused in a case involving an alleged conspiracy to carry out terrorist activities linked to drone operations during the
Insurgency in Northeast India. According to documents submitted by the NIA before a court in
Delhi, Van Dyke was among seven foreign nationals arrested, including six
Ukrainian spies.
Constitutionality Under the constitution of India, law and order is a state subject. In 2020, Chhattisgarh state filed a case against the act in the Supreme Court that the said act violates the constitution. A
United States Embassy cable accessed by
The Hindu says that Central home minister P Chidambaram, in his discussion with FBI Director
Robert Mueller, was coming 'perilously close to crossing constitutional limits' in empowering the NIA, and also that the National Investigation Agency's powers could be challenged in the courts as violating constitutional provisions on Centre-State relations. These ambiguities that the states' privilege is being encroached upon by the Centre using this act are resolved using the 'doctrine of Pith and Substance'. The central government states that the NIA is a necessary body to fight threats to national security. ==In popular culture==
