"If the captain of the organisation is indicted, then the whole organisation gets a bad name. After the court's direction, CBI's credibility is busted irreparably," TMC spokesman and Rajya Sabha member Derek O'Brien told PTI.
He alleged that "the CBI is used for political vendetta and to settle political scores".
The party said in its website, "The nation's worst kept secret: Using the CBI for political vendetta. So SC verdict means Credibility Busted Irreparably".
