New Delhi: The National Investigation Agency (NIA) on Thursday filed a massive 7,500-page chargesheet against 10 persons linked to the Red Fort car bomb blast. The high-intensity blast that occurred on November 10, 2025, involved a vehicle-borne improvised explosive device (VBIED), killing 11 people, injuring several others and causing massive property damage.The document filed before the NIA special court at Patiala House names 10 accused linked to Ansar Ghazwat-ul-Hind (AGUH), the branch of al-Qaeda in the Indian Subcontinent (AQIS). The chargesheet, supported by 588 oral testimonies, 395 documents and over 200 material exhibits, details how the group procured specialized laboratory equipment such as MMO anodes and electronic circuits from both online and offline sources. The accusers also include the alleged mastermind, Dr Umar Un Nabi, a former assistant professor of medicine at Al-Falah University in Faridabad. While Nabi is now dead – his identity has been confirmed through DNA fingerprinting – the charges against him are proposed to be dropped, while proceedings against Aamir Rashid Mir, Jasir Bilal Wani, Dr Muzamil Shakeel, Dr Adeel Ahmed Rather, Dr Shaheen Saeed, Mufti Irfan Ahmed Wage, Soyeb, Dr Bilal Naseer Malla and Yasir Ahmed Dar continue.The NIA’s detailed investigation, spanning Jammu and Kashmir, Haryana, Uttar Pradesh, Maharashtra, Gujarat and Delhi NCR, paints a chilling picture of a conspiracy involving radical medical professionals. According to the agency, after a failed attempt to migrate to Afghanistan via Turkey, the accused met secretly in Srinagar to form “AGUH Interim” in 2022. Under this banner, he launched “Operation Heavenly Hind”, aimed at overthrowing the Indian government to impose Sharia rule. The investigation revealed that the group manufactured triacetone triperoxide (TATP) explosives using commercially available chemicals and conducted experiments to perfect the mixture. Evidence suggests the module was also experimenting with advanced weaponry, including rockets and drone-mounted IEDs, aimed at targeting security installations across India.Apart from the explosives, the NIA found that the accused had illegally stored banned weapons, including AK-47 and Krynkov rifles. Searches conducted at Al-Falah University and various locations in Jammu and Kashmir provided forensic and voice analysis data that strengthened the case. While 11 people have been arrested in connection with case RC-21/2025/NIA/DLI, the NIA confirmed that efforts to track the remaining fugitives are still on. The accused face multiple charges under the UA(P) Act, Indian Justice Code, Explosive Substances Act, Arms Act and Prevention of Damage to Public Property Act.
