More than Rs. 300 crore in "undisclosed income" has been found in raids on Karnataka minister DK Shivakumar and his family and associates, sources in the income tax department told NDTV on Saturday as they countered charges that the action against the leader of the Congress party, which sits in the opposition at the Centre, was politically motivated. About Rs. 100 crore of this was found from Mr Shivakumar, or DKS as he is known, and his family, they said. The tax department, however, is yet to issue an official statement.
