He is missing since. That is one reason why theories of a “suicide attack” gained credence in the preliminary investigation.Umar's family members, including his mother, have been called for DNA tests to confirm if he was among the dead. So far, six of the 13 bodies remain unidentified. “Yes, as per our initial probe, Umar was driving the car and is probably dead. We are checking with the doctors at the mortuary,” said an officer, as per an HT report.Tracing the car’s ownership became the key that unlocked the Faridabad connection, police said, adding, “It was a long trail before we reached him (Umar).” The car was registered in the name of a man named Salman, who had sold it to a man named Devender. Both were detained, at which Devender said he had sold it to a man named Taariq. "While we were looking for Taariq, we found that the car was last with Umar,” said one of the investigating officers.How Faridabad link was foundPolice in Haryana, meanwhile, also identified Dr Umar Un Nabi as one of the key operatives connected to the recovery of nearly 2,900 kilograms of explosives and inflammable material from Faridabad’s Dhauj and Fatehpur Taga villages. They suspect that Umar transported the explosive material from a rented room in Faridabad and used it in Delhi.Umar worked as a doctor at Al-Falah Medical College in Faridabad for the last three years. That's the same institution where Dr Muzammil Shakil, arrested in the Faridabad terror module case, worked too.Another doctor arrested in the Faridabad case — Adeel Ahmad Rather, a former Senior Resident at Government Medical College, Anantnag, J&K — is believed to have played an active role in planning the Red Fort operation alongside Umar Un Nabi, officials told HT.Police in Faridabad have been scanning CCTV camera footage from multiple areas to trace the movements of Umar Un Nabi and Shakil to determine whether they travelled together to Delhi to plant the ammonium nitrate.“The network runs deep and is under active investigation. We are verifying how long Dr Umar Un Nabi had been employed in Faridabad and the extent of his involvement with the others,” Faridabad assistant police commissioner (crime) Varun Dahiya told HT.Investigators said Umar and Shakil had rented two accommodations in Dhauj for ₹1,200 and ₹1,400 a month, paying two months’ security deposit each. Both worked together to stockpile explosives and coordinate movements, probe officials said.Also read | Delhi 10/11 blast: How cops zeroed down on Pulwama doctor Umar Un Nabi, Faridabad linkInvestigators are also looking into whether the Red Fort blast was triggered by a device in the car that may have gone off accidentally. The intensity and heat of the explosion suggested the use of ammonia gel or a similar high-intensity explosive, they said.Action in J&KPolice in J&K also carried out raids and picked up six people, including three family members of Umar Un Nabi.For the past five days, J&K Police have carried out raids on dozens of houses across Jammu and Kashmir as, the sources said, there were fears of a terror attack. “The raids were being carried out as a preventive measure,” the spokesman said.(with inputs from Jignasa Sinha, Leena Dhankhar)
