New Delhi: Dayanidhi Maran, the Communications Minister during the first United Progressive Alliance (UPA) regime, faced yet another blow when the Central Bureau of Investigation (CBI) did not give clean chit to him in the 2G spectrum allocation scam.

The CBI stated that the verdict on Maran’s FIR would come up by September-end.

On the other hand, the NGO CPIL has filed a petition in the Supreme Court against the CBI for not investigating the case properly.

A CBI official said, during the investigation it was found that Maran had deliberately delayed Aircel's application for UAS licence and spectrum with a view to pressurise its promoter C Sivasankaran to strike a deal with Maxis, a Malaysian telecom firm. It is also alleged that Aircel's file gained momentum only after Maxis bought stakes in the company. 

However, the investigating agency has not yet found the evidence of any pressure on Sivasankaran to strike a deal with Maxis.
