Investigators working on the blast, who asked not to be identified, said they used CCTV footage to trace the car's movement in the final few hours in the buildup to the deadly explosion.

They said the footage shows the car, with three occupants, heading from the Daryaganj Market towards the Sunehri Masjid parking lot beside the Red Fort on Shantivan Marg around 4pm.

About two hours later, it was seen leaving the parking lot, taking a U-turn near Old Delhi Railway Station, and proceeding towards Lower Subhash Marg. "It was being driven on the Chhata Rail Chowk stretch before taking a U-turn and moving towards Lower Subhash Marg. The footage shows the car slowing down at a signal when the explosion occurred," said an officer aware of the investigation. All three occupants were killed instantly.
