The IT department raided the houses of some IAS officers and businessmen in Chhattisgarh and Madhya Pradesh in the past two days.
Chhattisgarh's Bharatiya Janata Party government is waiting for a final report from the IT department about Agriculture Secretary B.L. Agrawal's assets to initiate action against him.
IT officials searched the residence of Agrawal as well as business establishments of his close relatives Thursday.
On Friday, the officials similarly raided his chartered account Sunil Agrawal's house and came across documents suggesting that the IAS officer had amassed assets disproportionate to his known income.
The officer had at least 220 bank accounts, several of them opened on fake names and addresses, and a few in the names of his domestic helps.
Efforts by IANS to contact B.L. Agrawal failed. A man who answered his mobile telephone said Agrawal was "busy in a meeting".
Income Tax department sources said they were analysing the documents and papers they seized. Some documents suggest he might be involved in hawala transactions, the sources said.
