New Delhi, June 28 -- The National Investigation Agency (NIA) filed a second charge sheet against three more people in the November 2025 car bomb explosion near Delhi's Red Fort including an absconding doctor, and two overground workers (OGWs) of terror groups, the agency said on Saturday. One of the key people named in the second charge sheet, Muzafar Ahmad alias Faraz, paediatrician (MBBS, MD), is absconding. The other two are Zameer Ahmad Ahangar and Tufail Ahmad Bhat. The federal anti-terror probe agency in a statement said that Muzafar Ahmad was the founding member of al-Qaeda affiliated Ansar Ghazwat-ul-Hind (AGuH) and also a "prime architect" of the bomb blast conspiracy, in which 12 people including the bomber - Dr Umar un-Nabi - were killed. Earlier, four doctors including his younger brother - Adeel Ahmad Rather - were charged among 10 people in the previous charge sheet filed on May 14 naming 10 accused. "Absconding accused Muzafar Ahmed has been identified as the elder brother of co-accused Dr Adeel Ahmed Rather (arrested) and a founding member of AGuH Interim - an offshoot of al-Qaeda. NIA investigation revealed Muzafar Ahmed to be one of the prime architects, along with co accused Umer, Muzammil Shakeel, Adeel Rather, and Mufti Irfan, of the conspiracy that led to the deadly vehicle-borne improvised explosive device (VBIED) blast," NIA said in its statement. "Muzafar Ahmed attended the secret Eidgah meeting at Srinagar in June 2022, during which the terror module AGuH 'Interim' was established," the agency said, adding that he was deeply involved in the manufacture, testing and safekeeping of TATP-based improvised explosive device (IEDs) at a clandestine IED facility run by Dr Umer un-Nabi and and Muzammil Shakeel at Al-Falah University in Faridabad'. A non-bailable warrant has been issued against him and efforts are being made to trace him, the agency said. NIA said that Zameer Ahmad Ahanger worked for this offshoot and was "actively in touch with handlers", and "acted as a courier for arms, ammunition, and cash for the terror module". The third accused, Tufail Ahmad Bhat, is a former OGW of the Lashkar-e-Taiba (LeT) and worked as its "arms supplier"....
