New Delhi: Delhi Police Special Cell has obtained a CCTV footage showing a car dropping off two persons who walk towards the spot near the Israel Embassy where a minor explosion took place on Friday evening.
A team of investigators from Israel will assist Indian agencies in the probe over the blast in which some cars were damaged in the high-security zone of Lutyens' Delhi.
The driver of the vehicle has been traced and sketches of the two people are being prepared. A probe has been initiated to ascertain their involvement in the blast.
An envelope addressed to the Israeli Embassy and containing a note was found at the site of the blast, sources had said on Friday.
According to news agency IANS, the letter says the explosion was just a "trailer" and also mentions Iran's General Qasem Soleimani and top nuclear scientist Mohsen Fakhrizadeh as "martyrs".
Both were assassinated last year. Soleimani was killed near the Baghdad International Airport in a drone strike ordered by then US President Donald Trump on January 3.
Friday's blast took place 1.4 km from Vijay Chowk, where the President and Prime Minister and other senior members of the government had assembled for the Beating Retreat ceremony.
The Delhi Police said that the improvised explosive device (IED) went off at 5.05 pm and no one was injured and there was no damage to any property.
A high alert has been sounded in the capital and security at the airport and other strategic locations have been intensified.
