Unitech denied that Chandra's voice was on any alleged

recording and said it appeared a fabricated voice recording had been sent anonymously to CBI. "It is nothing but an attempt to malign him and prejudice his defence in the 2G case," the Unitech statement said. CBI Director Ranjit Sinha said since the prosecutor has come under a cloud, he has been transferred from the case. Unless the inquiry is completed, CBI cannot take action against Singh, he said. Sinha said while he cannot confirm the genuineness of the tape, prima facie it appeared to be true. But only a forensic examination would give the correct picture, he said. The CBI Director also ruled out the case being compromised and said a "trivial aberration" by one person cannot compromise the "honesty and integrity" of the investigation agency.
