New Delhi, Jan 30 (IANS): Delhi Police Special Cell has obtained 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.
The team of investigators from Israel could arrive in New Delhi as early as Saturday to 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.
A letter has also been recovered from the site of the blast that mentions the explosion was just a "trailer".
Sources said that the letter 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.
A high alert has been sounded in the capital and security at the airport and other strategic locations have been intensified.
