The registration of FIR followed a preliminary enquiry initiated by the agency in April.
"It has been alleged that the minister while functioning as a public servant has amassed assets disproportionate to his known sources of income to the extent of Rs 1.62 crore (approx) during the period of February 14, 2015 to May 31, 2017.

"So far, this has led to recovery of certain incriminating documents," he said.
The CBI said during enquiry, it was found that the minister and his associates were allegedly involved in money laundering to the tune of Rs 4.63 crore during 2015-16 through shell companies based in Delhi.
"This apart, before becoming public servant, he was allegedly involved in laundering of Rs 11.78 crore during the years 2010-12 through these companies as well as other companies also based in New Delhi," it said.
"Although, he had resigned from directorship of the three companies in 2013 before contesting election, however, his investments in these companies were allegedly continued," the spokesperson said.
The official said it was further alleged that the companies did not have any business and were shell companies and were utilised for parking money in the form of investments in equity shares in connivance with Kolkata-based shell companies.
