New Delhi, Nov. 12 -- The probe into the deadly car blast near the Red Fort was on Tuesday handed over to the premier anti-terror agency NIA. The car that exploded on an arterial road near Red Fort in Delhi on Monday evening has been traced to a Kashmir based doctor with ties to a terror module linked to the seizure of a huge cache of explosive material in Faridabad, two officers from Delhi Police's Special Cell said on Tuesday. The doctor, identified as Dr Umar Un Nabi from Pulwama, was in contact with two other doctors from Jammu and Kashmir arrested recently and was probably driving the white Hyundai i20 car when it exploded after slowing down near a red light, these officers said on condition of anonymity. The explosion engulfed nearby vehicles and left 13 people dead and 21 injured. Delhi Police registered a first information report to investigate the case under provisions of the Unlawful Activities (Prevention) Act that deal with terrorism, sections of the Bharatiya Nyaya Sanhita (BNS) on murder and attempt to murder, and the Explosives Act. The links between Monday's explosion and the Faridabad module were discovered in the course of investigations into the ownership of the i20. "It was a long trail before we reached him (Umar). The car was registered in the name of a man named Salman who revealed he sold it to a man named Devender. Devender was picked up and he said he 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 officers. We were searching for him and then found that he was inside the i20 at the time of the attack. We also found that he works in the same module as his doctor friends - Muzammil Shakil and Adil Ahmed- who were caught with 2800 kgs of RDX material," the officer added. The second officer said, "Yes, as per our initial probe, Umar was driving the car and is probably dead. We are checking with the doctors at the mortuary. He planned all this and executed this after his friends got arrested." MORE ON PAGE 2...
