The Enforcemen Directorate on Tuesday questioned Delhi Health Minister Satyendar Jain in connection with a money laundering case.
The case pertains to alleged transfer of more than ₹16 crore from Kolkata-based shell companies to the firms in which Mr. Jain had stakes.
The agency alleges that about ₹4 crore had been laundered during Mr. Jain's tenure as a Minister in the Delhi government.
"The shell companies first bought the shares of his companies at a high premium, after which the shares were bought back at very low rates," said an official.
The ED may again summon Mr. Jain and his associates for recording their statements.
