Dayanidhi Maran has come under the Central Bureau of Investigation?s (CBI) scanner again. The agency is examining his alleged role in sanctioning spectrum to Sun Direct.

The agency had asked the Department of Telecommunications (DoT) for the files pertaining to spectrum allocation made to direct-to-home (DTH) broadcasters by examining the details of the sanction of bandwidth.

The decision to probe DTH broadcasters was taken after the agency found that a few of the telecom companies being examined in relation to the 2G spectrum issue were also broadcasters of the service.

The files pertained to Dish TV India Limited, Reliance Big TV Limited, Bharti Multimedia Limited, Bharti Business Channel Private Limited, Doordarshan, Sun Direct TV Private Limited and Tata Sky Limited.

However, it is believed that apart from Sun Direct, all other files were returned to DoT by the CBI.
