Six months after the Red Fort car explosion that killed 11 people and injured several others on November 10, 2025, the National Investigation Agency on Thursday filed a 7,500-page chargesheet in the case before a special NIA court at Patiala House Courts in New Delhi.All 10 accused, including the main perpetrator Umar Un Nabi—who allegedly drove the explosives-laden car and is now deceased—have been linked to Ansar Ghazwat-ul-Hind (AGuH), an offshoot of Al-Qaida in the Indian Subcontinent (AQIS), according to the chargesheet.The Tribune had earlier reported that the NIA was looking at the possibility of the involvement of a relatively unknown outfit behind the incident. The organisation AQIS and its manifestations were designated as terrorist organisations by the Ministry of Home Affairs in June 2018.The chargesheet has been filed under relevant sections of the UA(P) Act 1967, Bharatiya Nyaya Sanhita 2023, Explosive Substances Act 1908, Arms Act 1959, and Prevention of Damage to Public Property Act 1984.Charges against Pulwama-based Umar Un Nabi, who was a former assistant professor of Medicine at Al-Falah University in Faridabad (Haryana), have been proposed to be abated.Apart from Nabi, others named in the chargesheet are Aamir Rashid Mir, Jasir Bilal Wani, Dr. Muzamil Shakeel, Dr. Adeel Ahmed Rather, Dr. Shaheen Saeed, Mufti Irfan Ahmad Wagay, Soyab, Dr. Bilal Naseer Malla and Yasir Ahmad Dar.The high-intensity Vehicle-Borne Improvised Explosive Device (VBIED) blast that had rocked the national capital on November 1002025 had also caused extensive damage to the property.The chargesheet is based on extensive investigation spread across the states of Jammu & Kashmir, Haryana, Uttar Pradesh, Maharashtra, Gujarat and the Delhi NCR region. It includes detailed evidence in the form of 588 oral testimonies, more than 395 documents and over 200 seized material exhibits.As per the chargesheet, the NIA has unravelled a major Jehadi conspiracy through detailed scientific and forensic investigation, had found the accused, some of whom were radicalised medical professionals, to have been inspired by AQIS/AGuH ideology to carry out the deadly attack.At a clandestine meeting in Srinagar in 2022, the accused had reconstituted the AGuH terror outfit as “AGuH Interim” following a failed Hizrat to Afghanistan via Turkey. Under the umbrella of the newly constituted outfit, they had launched “Operation Heavenly Hind” aimed at overthrowing the democratically established Indian Government and imposing Sharia rule.NIA investigation revealed that, as part of the Operation Heavenly Hind, the accused had recruited new members, actively propagated the violent Jehadi ideology of AGuH, stockpiled arms and ammunition, and manufactured explosives on a large scale using commercially available chemicals.The accused had also fabricated and tested various types of IEDs, NIA found during its investigation in the case.The explosive used in the blast was Triacetone Triperoxide (TATP) which was manufactured by the accused clandestinely procuring constituent ingradients and conducting experiments to perfect the explosive mixture.NIA, which had taken over the investigation from Delhi Police, had established the identity of the deceased accused as Umar Un Nabi through DNA fingerprinting.Evidence collected from the scene of the crime, as well as various locations identified by the accused in and around the Al Falah University in Faridabad as well as Jammu & Kashmir, were subjected to thorough forensic examination, voice analysis etc. as part of the investigation.The NIA probe had further revealed that the accused had also been involved in illegal procurement of prohibited arms, including an AK-47 rifle, a Krinkov rifle, and country-made pistols with live ammunition.They had experimented with rocket and drone-mounted IEDs with the objective of targeting security establishments in the state of Jammu & Kashmir and other parts of India.It was also revealed during the investigation that the accused procured laboratory equipment including specialised items like MMO Anode, electric circuits, and switches from various offline and online sources.The accused also had plans to expand their operations in other parts of the country, which were foiled by the busting of the terror module.A total of 11 persons have so far been arrested in the case, in which NIA is continuing with its efforts to track absconders whose role had surfaced during the investigation.Earlier, a Delhi court on February 13 allowed the NIA an additional 45 days to submit its chargesheet in the case.The anti-terror agency had approached the court of Additional Sessions Judge Prashant Sharma of Patiala House, seeking a 90-day extension to complete its investigation. However, the court granted only half of the requested period and instructed the agency to wrap up the probe within the revised deadline.
