The Income Tax Department has detected unaccounted income of Rs 400 crore after it raided a Pune-based company engaged in dairy farming and manufacturing of milk products, the CBDT said.

The searches were launched on November 24 at thirty premises located in half-a-dozen cities. "The search operation has resulted in the seizure of unaccounted cash and unexplained jewellery of about Rs 2.50 crore while some bank lockers are yet to be operated," the CBDT said in a statement.
