Senior IPS officers from Delhi Police's anti-terror units and officials from the National Investigation Agency have also reached the spot. "We are looking into the matter. Multiple police teams have been rushed to the spot. It is yet to be ascertained the kind of material that exploded," an officer said. As per fire department information, they received the call at 5.11 pm, and three fire tenders were pressed into service. The window panes of the vehicles parked in the nearby area have been damaged.

Delhi Police had then arrested journalist Syed Mohammad Ahmad Kazmi for aiding bike-borne bombers who are yet to be caught.
