New Delhi, June 8 (IANS): The Delhi government is likely to complain to President Pranab Mukherjee about Lt. Governor Najeeb Jung "hampering" the probe into the Rs.100 crore transport scam that took place under the previous Sheila Dikshit government, an official said on Monday.

"We are likely to take up the matter with the president. The Central Bureau of Investigation (CBI) was denied sanction to question officials in the scam," a government official told IANS.

"Jung had closed the case and the CBI asked the Delhi government vigilance department to hand over the case to the Anti Corruption Branch," he added.

The Delhi government's ACB has decided to relaunch investigation in the case.

In 2012, the ACB had registered a case in the alleged loss of Rs.100 crore to the Delhi government in awarding the contract of operation and maintenance of inspection and certification of CNG vehicles.

However, the then Dikshit government had denied permission to the ACB when it demanded to question certain officials.

In January 2014, the CBI initiated a preliminary inquiry in the case and was assured all help by the then Aam Aadmi Party government.

But after Arvind Kejriwal resigned as chief minister in February 2014, "the case got stuck again", a source said.
