New Delhi: The National Investigation Agency (NIA) has laid out startling details in its chargesheet in the Red Fort blast case, revealing that accused Umar-un-Nabi adopted an extraordinary method to collect raw materials for manufacturing explosives. According to the agency's filings, Nabi stored human urine inside polythene bags while he was in hiding in the Nuh area of Mewat. The bizarre finding came to light only after a foul smell emanating from the premises drew the attention of the local house owner, who lodged a complaint with authorities.

Upon conducting a search of the location, NIA operatives discovered pen drives containing PDF documents that outlined the step-by-step preparation of urea nitrate — a powerful improvised explosive compound that can be made using urea, a primary ingredient found in urine, combined with nitric acid. The explosive manual files formed a critical piece of evidence linking Nabi directly to the planning and execution of the Red Fort blast.

The NIA has also traced these activities to a revived module of Ansar Ghazwat-ul-Hind, a banned extremist organisation that pledged allegiance to the Islamic State (ISIS). The agency alleges that the newly reactivated network was allegedly led by Umar-un-Nabi himself, and was involved in conspiring to carry out attacks on sensitive targets across the national capital region.

Umar-un-Nabi is already one of the key accused in the February 2020 Red Fort blast, which occurred during the Maha Shivaratri celebrations when a bomb exploded near the historic monument, injuring several people. The attack had sent shockwaves across the country and prompted a massive manhunt by central investigating agencies.

Legal proceedings against Nabi are now underway, with the NIA presenting its evidence before a designated court. The agency continues to pursue additional associates linked to the expanded militant module operating in the Mewat region, where several such cells have been reported to have taken root in recent years.
