"It is a lie. I was strenghtening the evidence and not tampering with it," he said.
He went on to add that the scam is of 116 crore involving letters of credit. "The fraud was committed by three people, who were trying to grab media attention last year," he said.
Speaking about the case he said that 'a desk officer named Pavan Kumar was made the only accused. Rest all escaped," he said.
He even said that he would make the transcripts of the conversations with the witness public, just to prove that the allegations were wrong.
He then requested the CBI to nab the culprits and not see this as a case of evidence tampering.
