New Delhi, Nov. 17 -- With confirmation that 35-year-old MBBS doctor from Jammu and Kashmir, Umar Un Nabi, who executed the deadly car blast outside Red Fort on Monday evening, was using two mobile phones, teams investigating the blast case and another related case to probe a "larger conspiracy" behind the terror attack are now trying to recover his cellphones that could lead them to key conspirators and unravel their pan-India terror strikes plan, police officials privy to the cases said. A CCTV footage that surfaced on Saturday showed Umar sitting inside a shop in Haryana's Dhauj with a bag and two mobile phones on October 30. He was seen in the footage giving one mobile phone to a person at the shop reportedly for charging while the other phone remained with him. The police are trying for CCTV footage that could show Nabi with the mobile phone between the night of November 9 and November 10 evening, when the blast happened. Investigators suspect that Nabi either dumped the phones somewhere while driving the white Hyundai i20 in Faridabad and Delhi from the night of November 9 and before the blast at 6.52 the next day or gave them to someone he met during the journey. The blast claimed at least 11 people. While the investigating teams have found the footage of more than 50 CCTV cameras, confirming Nabi's car journey in Haryana's Faridabad and Mewat region apart from multiple places in south, east, central and north Delhi, they have focused their probe on the four locations.
