A CNG cylinder blast near Prime Minister Manmohan Singh's residence on Monday created a flutter among security agencies including elite SPG guarding the VVIP.
Three people received minor injuries in the incident at 2pm at a petrol station located 200 metres from 7 Race Course
Road, the official residence of the Prime Minister.
The CNG cylinder inside a vehicle burst apparently due to excess pressure when it was being filled up, officials said.
A high alert was immediately sounded and police rushed to spot to ascertain the nature of the blast.
