"Day before yesterday they had asked for details only about the two new franchises - their shareholding patterns, addresses, player auction and bidding process etc. Now they want us to furnish all the details about the eight other franchises too," Prof Ratnakar Shetty, Chief Administrative Officer of the BCCI, said on Sunday.

Apparently the IT authorities are investigating the entire IPL structure, which has become a huge revenue-earning entity for the BCCI, since its inception in 2008.

Shetty said IPL chairman Lalit Modi or CEO Sundar Raman would be representing the Board during the summons on April 23.

The eight original franchisees are: Reliance Industries Limited for Mumbai franchise at $111.9 million; UB Group for Bangalore at $111.6 million; Deccan Chronicle Holdings for Hyderabad at $107.01 million; India Cements for Chennai at $91 million, GMR for Delhi at $84 mn, Red Chillies Entertainment (Shah Rukh Khan/Juhi Chawla/Jay Mehta) for Kolkata at $75.09 million; Preity Zinta, Ness Wadia, Mohit Burman and Karan Paul for Mohali at $76 million; Emerging Media (UK) for Jaipur at $67 million.
