The CBI questioned Delhi Health Minister Satyendar Jain for the second consecutive day on Friday in connection with a money laundering probe.
Jain was questioned at the Central Bureau of Investigation (CBI) headquarters in south Delhi's Lodhi Road area for around five hours.
"Jain was again questioned by the CBI officers at the headquarters in a money laundering case. He appeared before the investigators around 3 p.m. and was questioned till 8 p.m.," a CBI official told IANS.
On Thursday, he was questioned by the CBI for around eight hours.
The CBI in April launched probe against Jain and registered a preliminary inquiry against the Aam Aadmi Party (AAP) leader, who is known to be close to Delhi Chief Minister Arvind Kejriwal.
The agency registered the preliminary inquiry against Jain based on the evidences it had collected against him in connection with money laundering totalling Rs 4.63 crore in 2015-16.
He is accused of being involved in the crime through Kolkata-based companies Prayas Info Pvt Ltd, Akichand Developers and Mangalyatan Project Pvt Ltd.
Jain 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.
Thereafter, the 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 -- all controlled by Jain, the CBI official said.
"The shares were bought at a premium of 60 times the unit price."
Jain had technically resigned from the directorship of the companies in view of the 2013 Delhi assembly election, the official said, adding that the money received back in the form of investment in shares was used by him for purchasing agricultural 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 land 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 the scanner over allegations of hawala transactions of nearly Rs 17 crore.
Jain had earlier said he made investments in these companies as an investor four years back but had withdrawn from those since 2013, and that he had done nothing wrong.
IT officials also found 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.
