The Central Bureau of Investigation has taken the voice samples of its sacked public prosecutor A K Singh and Managing Director of Unitech Sanjay Chandra for matching them with the audio tape purportedly carrying conversation between the two discussing ways to weaken the 2G spectrum allocation case.

The voice samples had been sent for forensic examination along with the CD which purportedly contains their voice samples in which Singh is said to suggest how a key prosecution witness would depose in the special court hearing the 2G case.
The CBI, which had received the CD ten days ago from its “source”, has already registered a preliminary enquiry against Singh and Chandra based on prima facie evidence.

Recording in Sept

It is said that the conversation was recorded in September last year by some private agency. Chandra is key accused in the 2G scam and currently under bail. The agency, while taking note of the CD, immediately removed Singh from the case and CBI Director Ranjit Sinha informed the Supreme Court as well as the Law Ministry about the decision.

Sinha, appearing before the Joint Parliamentary Committee (JPC) probing 2G spectrum allocation, said that this incident has not “polluted” the probe into the case but admitted that the agency’s reputation suffers by such incidents.

Not polluted

Describing the incident as an “eye-opener”, the CBI chief told the panel that even the agency was surprised by the alleged development as it has counter-intelligence mechanism in place which could not detect it.

“The CBI Director clarified that A K Singh is one of the prosecutors (in the 2G case) assisting chief prosecutor U U Lalit appointed by the Supreme Court...He (Sinha) said Singh was only one of the prosecutors, therefore, the investigation into the case has not been polluted,” JPC Chairman P C Chacko told reporters after the meeting.

Chacko said the JPC would not call Singh and Chandra as witnesses as their alleged conversation was not part of the terms of reference of the JPC.
