New Delhi, Apr 24 (PTI): The CBI in its second charge sheet likely to be filed on April 25 may name Tamil Nadu chief minister M Karunanidhi's daughter Kanimozhi, wife Dayalu Ammal and several others for allegedly getting benefits out of the allocation of 2G spectrum to certain telecom firms.

The chargesheet to be filed in the court of Special CBI Judge O P Saini may give details as to how over Rs 200 crore was illegally routed by jailed former telecom minister A Raja, his slain aide Sadiq Batcha and Shahid Usman Balwa, the former Managing Director of DB Realty to DMK-owned Kalaignar TV, jointly owned by Kanimozhi, Dayalu Ammal and Sharad Kumar.

Kanimozhi, Dayalu Ammal and Kumar, Managing Director of the TV, have 20, 60 and 20 per cent shares in the channel respectively.

The CBI had earlier told the court that Rs 200 crore connected with the 2G spectrum scam had travelled from a partnership firm of Balwa to Kalaignar TV.

The agency had said the money travelled through a "circuitous route" through Kusegaon Fruits and Vegetables Pvt Ltd, a DB group company and Cineyug Films Pvt Ltd.

"Investigations have also revealed that in furtherance of the conspiracy, Dynamix Realty, a partnership firm of DB Realty Ltd and other DB group companies, paid Rs 200 crore to Kalaignar TV Pvt Ltd during December 2008 to August 2009, following a circuitous route through Kusegaon Fruits and Vegetables Pvt Ltd and Cineyug Films Pvt Ltd (DB group holds 49 per cent equity in it)," CBI said in its first charge sheet filed on April 2.

Besides, the second chargesheet may also throw some light on the role of Batcha who died in mysterious circumstances last month (March).

Names of Asif Balwa, cousin of Shahid Balwa, and Rajeev Agarwal, Directors of Kusegaon Fruits and Vegetables Pvt Ltd, who are presently in judicial custody, are also expected in the supplementary charge sheet.

Raja and eight others, including former telecom secretary Siddharth Behura and three telecom companies were on April 2 indicted in the 2G spectrum allocation scam by CBI, which pegged the loss to the exchequer at Rs 30,984 crore.

The first chargesheet has named Behura, Raja's former PS R K Chandolia, Unitech MD Sanjay Chandra, Swan Telecom promoters Shahid Balwa and Vinod Goenka, Reliance ADA group's Gautam Doshi, Surendra Pipara and Hari Nair, Reliance Telecom, Unitech Wireless and Swan Telecom.

The CBI has informed the Supreme Court that the supplementary chargesheet will be filed before April 25 in the special court of Justice O P Saini and the probe in the case will be completed by May 31.
