"The biggest case is against Mukesh Ambani, Moily. The investigation of this case should not be hampered. We have also registered five cases against Delhi Jal Board and in the Common Wealth Games. These cases are both against the Congress and the BJP.
"The investigation of these cases should not be hampered," said Manish Sisodia, who was a senior minister in the AAP government.
Early this week, the AAP government had registered an FIR against Mukesh Ambani, Union Petroleum Minister Veerappa Moily and former petroleum minister Murli Deora over gas pricing.
"In coming days, the ACB will not be under our control. Our request to coming regime is not disturb the investigation. We will be keeping a close eye on the investigation," he added.
