New Delhi:In a shocking revelation during the National Investigating Agency's (NIA) probe into the November 10 car blast near theRed Fort, which killed 15 people and injured several others, it has emerged that five arresteddoctorscollectively raised Rs 26 lakh to finance the bombing operation. The funds were reportedly used to purchase weapons and manufacture explosives for the 10/11 attack. Each doctor contributed different amounts, more than Rs 5 lakh in some cases and less in others, adding up to a total of Rs 26 lakh. Using this fund, the group planned coordinated terror attacks across multiple cities. Among the five doctors were the female doctor and the doctor who drove the Hyundai car to the blast site and died in the suicide bombing. Out of the five, two contributed Rs 5 lakh each, one gave Rs 8 lakh, another Rs 6 lakh, and the suicide bomber contributed Rs 2 lakh.

During questioning, the NIA also found that one of the doctors bought a Russian assault rifle for Rs 5 lakh through a contact connected to the female doctor, who is suspected to be the mastermind of the white-collar terror module. The rifle was the same one which recovered from the locker room of a doctor at a government medical college a few days ago. The doctor also admitted to procuring 26 quintals of NPK fertiliser from Gurugram and Nuh for approximately Rs 3 lakh. “He was responsible for sourcing fertiliser and other chemicals. They were not building explosives overnight; it was being planned meticulously,” an NIA official toldHT. The fertiliser was allegedly converted into explosive material under the supervision of the doctor (suicide bomber), who also arranged remote detonators and circuitry. recently reported how an ordinary flour mill grinder became a key tool for the arrested doctor from Pulwama to turn chemical substances into explosives. The National Investigating Agency (NIA) investigating the case found the explosive-making setup at the house of a taxi driver in Faridabad. The Pulwama doctor, who played a major role in the Delhi blast case, apart from the Al-Falah assistant professor, had rented a room there and stored a flour mill, a grinder, and other electronic machines. He used this rented space to prepare explosives by grinding urea and separating ammonium nitrate from it to refine the material, and had been doing this for a long time. It was from this same room that police recovered 360 kg of ammonium nitrate and other explosive substances on November 9 - a day before the deadly car blast in Delhi on November 10. Another NIA officer told HT, "The purported confession has helped link previously scattered leads. The scale of recovered materials has reinforced suspicions of a plan to carry out serial blasts rather than a one-off strike. The quantity they amassed cannot be for a single explosion."
