I-T officials said the tax department conducted searches against the officer here and in Balasore yesterday, following reports of huge deposits made by him and his family members in various bank accounts post demonetisation.
Efforts by PTI to reach the forest department officer concerned did not fructify.
They said while the department detected undisclosed assets worth Rs 3.67 crore, including bank deposits and land properties at a few locations, Rs 6 lakh in new notes (Rs 2,000/Rs 500) was recovered during the operations.
Income from agricultural sources is exempt from tax under law.
The officials said the officer was also found to be not filing any Income Tax Returns (ITRs) as he told the taxman that tax is deducted from his salary and hence he was not filing such returns.
"Further probe is on," an official said.
