Delhi Government confronts Delhi Lieutenant Governor Najeeb Jung on the multi-crore CNG fitness scam as Delhi Deputy Chief Minister Manish Sisodia questions L-G for calling the CNG inquiry null and void. Sisodia asked Ministry of Home Affairs (MHA) to approach judiciary if aggrieved. The CNG fitness scam surfaced in 2012 when ACB found out that Delhi government had lost over Rs 100 crore by the contract to operate and maintain certification of CNG vehicles at the transport authority in Burari being awarded to ESP India Pvt Ltd instead of ESP USA.
