The CBI on Tuesday said it has registered a preliminary inquiry against Delhi Health Minister Satyendar Jain in an alleged money laundering case. The AAP leader claimed he was innocent.

The agency registered the case on Monday on the basis of evidences it had collected against the minister, saying he was involved in money laundering totalling Rs 4.63 crore in 2015-16.

"Jain is accused of being involved in the crime through Kolkata-based companies Prayas Info Pvt Ltd, Akichand Developers and Mangalyatan Project Pvt Ltd," an official said.

Jain, a confidant of Delhi Chief Minister Arvind Kejriwal, is also accused of purported money laundering totalling Rs 11.78 crore in 2010-12 through these companies and Delhi-based Indo-Metal Index Pvt Ltd.

It was alleged that the money was given in cash by Jain through his employees and public associates to Kolkata-based entry operators and shell companies, the official said.

"Thereafter, entry operators routed the black money in the form of investment in shares of Prayas Info Pvt Ltd, Akichand Developers, Mangalyatan Project Pvt Ltd and Indo-Metal Index Pvt Ltd which were controlled by Jain," the official said.

They said the shares were bought at a premium of 60 times the unit price.

"Jain technically resigned from the directorship of the companies in view of the 2013 Delhi assembly election. The money received back in the form of investment in shares was used by him for purchasing agriculture land worth Rs 27.69 crore in Delhi in the name of companies controlled by him."

It was also alleged that Jain used his power as minister to get the agricultural land declared as residential area by the Delhi government in order to gain huge financial benefits, the official added.

The matter was referred to the CBI by the Income Tax Department against the new Benami Transactions Prohibitions Act.

The IT Department in September 2016 summoned Jain for his alleged links with the firms which were under scanner over allegations of hawala transactions of nearly Rs 17 crore.

Jain said he had made investments in these companies as an investor four years back but had withdrawn himself from them since 2013 and that he had done nothing wrong.

"I am being framed," Jain said. "All this is done to stop the policies started by the Delhi government. It is a politically motivated case."

IT officials received records of certain financial transactions connected to Jain after their counterparts in Kolkata searched a firm in connection with tax evasion and alleged illegal financial remittances.
