The Delhi Police spokesperson the blast was caused by a “very low-intensity improvised device” and there were no injuries.
However, the window panes of three cars parked near the blast site were damaged due to the explosion, the spokesperson said in a statement.
“A very-low intensity improvised device went off at 5.05 pm near 5 APJ Abdul Kalam Road near Jindal House,” the Delhi Police spokesperson said in the statement.
“No injury to any person is there and nor any damage to property was witnessed except window panes of three vehicles parked nearby. Initial impressions suggest a mischievous attempt to create a sensation,” the statement said.
