ED sources told PTI that Basu, also former chairman of Broadcast Media Worldwide (BMW), appeared before its officers today and gave his statement.
Later, Basu told reporters that ED special director Yogesh Gupta had asked him to appear before the agency in connection with the sale of Tara TV channels formerly owned by BMW to the Saradha Group.
Basu said he told the ED that although he was the chairman of BMW till 2011, the year when the sale transaction was effected, he was a minority shareholder with only 12 per cent stake.
The value of the deal was Rs 18 crore, while the value of his shares was Rs 31 lakh, which Basu claimed was never realised by him.
Shiva Ventures had got "some money" but not the entire amount, which was promised to be paid at a later date by Sen for which the Saradha chief had mortgaged one of his properties to the company.
