Spectrum controversy: CBI to conduct 'impartial' probe

"The CBI has registered a case and we are undertaking investigation. Let me assure you CBI will do a very impartial, correct and legal investigation," CBI Director Ashwini Kumar told reporters here.

Kumar said CBI would not go by the opinions of individuals, media or anybody else in its probe into the spectrum controversy, adding, "whatever evidence comes it has to be legally admissible"

"We are not going to go by the opinions of individuals, media or anybody.. it has to be a legal investigation and we have to have legal evidence.. there has been a lot of media, public and Parliament attention" on this case, he said.

Stating that legally admissible evidence was important, the CBI chief said "we are doing that investigation and we will continue to do that."

To a query, Kumar said once the agency takes up investigation of a matter, it confines itself to the allegations made in the FIR and "if something more comes up, we can register another FIR."
