The National Investigation Agency (NIA) has widened its investigation into the deadly Red Fort bomb blast case by filing a supplementary chargesheet against three more alleged members of the terror network behind the attack, including an absconding paediatrician accused of helping plan the conspiracy.

The latest chargesheet, filed before the Patiala House Court in New Delhi, names Muzafar Ahmad, Zameer Ahmad Ahanger and Tufail Ahmad Bhat. With their inclusion, the total number of accused chargesheeted in the case has risen to 13.

The blast, which took place near Delhi's Red Fort on November 10, 2025, killed 11 people and triggered a nationwide counter-terror investigation.

Who are the three newly chargesheeted accused?

1. Muzafar Ahmad: The Doctor Allegedly Linked to the Conspiracy

According to the NIA, Muzafar Ahmad, a paediatrician by profession, was among the key figures behind the terror plot and remains on the run.

Investigators allege that Muzafar was a founding member of Ansar Ghazwat-ul-Hind (AGuH) Interim, a group the agency describes as an offshoot inspired by Al-Qaeda's ideology. He is also the elder brother of co-accused Dr Adeel Ahmad Rather.

The agency claims Muzafar played a central role in the conspiracy alongside several other accused, including the deceased main accused Dr Umer Un Nabi. The NIA further alleges that he participated in a secret meeting in Srinagar in 2022 where the terror module was formed.

Investigators say he was involved in the development and handling of improvised explosive devices and helped facilitate activities linked to the group's operations. A non-bailable warrant has been issued against him, and efforts to trace him are continuing.

Zameer Ahmad Ahanger: Alleged Courier for the Module

The NIA has identified Zameer Ahmad Ahanger as an alleged overground worker associated with the terror module.

According to investigators, he maintained contact with handlers and played a supporting role in the movement of weapons, ammunition and funds. The agency alleges that he acted as a courier, helping the network transport resources required for its activities.

Tufail Ahmad Bhat: Alleged Arms Supplier

The third accused named in the supplementary chargesheet is Tufail Ahmad Bhat, whom the NIA describes as a former overground worker linked to the banned Pakistan-based terror outfit Lashkar-e-Taiba (LeT).

Investigators allege that Tufail arranged weapons for members of the module through a network of handlers. The agency claims he procured firearms and ammunition, including assault rifles and a pistol, before passing them on to the main accused.

The NIA believes the weapons were intended to strengthen the operational capabilities of the group involved in the conspiracy.

What has the investigation found so far?

According to the NIA, the case has been pieced together through forensic examinations, geo-location analysis, financial-trail tracking and other technical evidence.

The agency alleges that the conspiracy behind the vehicle-borne improvised explosive device (VBIED) attack involved multiple people operating across different locations and performing specialised roles ranging from logistics and financing to weapons procurement and bomb-making.

Officials said the investigation remains ongoing as the agency continues to examine the wider network, its handlers and possible links to other operatives.
