New Delhi: Facing heat from both Centre and Opposition, the Central Bureau of Investigation (CBI) is gearing up to tighten its noose around Union Textile Minister Dayanidhi Maran for his alleged role in the 2G spectrum allocation scam.The investigating agency is likely to begin a probe against him after filing an FIR.

The DMK leader is also in the line of fire over allegations of duping BSN by establishing 323 telephone connections at his Chennai based residence when he was Telecom Minister before A Raja.

The Union Minister has also been charged of favouring his family-owned Sun Television Network by making it a beneficiary of pay-offs by a Malaysian company which benefitted from equity sold by Aircel.

According to a senior official, Maran allegedly delayed awarding UAS licenses to Aircel which had been applying with the DoT since 2004 by raising irrelevant issues from time to time ignoring the request of its owner C Sivasankaran to resolve them, following which he sold the company to Malaysia based Maxis group.

Notably,last month Sivasankaran himself came forward and decided to record his statement against Maran.Soon, the CBI is going to record his statement. Though, the CBI officials have maintained that his statement is unnecessary as they have sufficient evidence against the Union Minister to file a chargesheet.

Earlier,CBI in its progress report filed on the orders of the Supreme Court regarding the scams occurred between 2001 and 2007 had included Aircel’s licence scam too.

Taking a note of BSNL fraud,CBI is mulling to report 323 telephone usage matter from 2004 to 2007 to the telecommunications department too.

“The agency tried to get the records from the telecommunication department but in vain. However, in case of any evidence from the department, CBI will probe his role and might file a FIR against Maran”, sources said.

Notably,with prevailing call rates the loss to BSNL can be as high as Rs 440 crore.
