The National Investigation Agency (NIA) has alleged in its chargesheet in the 2025 Red Fort blast case that members of the accused terror module accessed and circulated extremist literature, including the Lone Mujahid Pocket Book, also referred to as How to Become an Assassin.
According to the agency, the document was linked to Al-Qaida in the Arabian Peninsula (AQAP) and allegedly contained operational material relating to explosives, weapons, covert activities and improvised explosive devices. The chargesheet forms part of the investigation into the car blast near Delhi’s Red Fort on November 10, 2025, which killed 11 people and injured 29 others.
