‘It’s Amar voice on the tapes’

Sources in the laboratory’s Government Examiner of Questionable Documents department say the conversations, both in English and Hindi, are mostly of a routine nature and that many calls were in fact first received by Singh’s personal secretary. ‘‘There is nothing sensational in the contents of the tapes. There is no female voice on the tapes we were sent, but there are more recordings which are still to come to us. The entire material has not arrived here yet,’’ the sources said.

Earlier this month, the Delhi Police sent the sealed CD running into 20 hours to the Hyderabad Forensic Laboratory for ‘‘determining the authenticity’’ of the tapes. The Delhi Police—which had made the CD case property after recovering it from detective Bhupendra Kumar—will now be attaching the laboratory report to the case chargesheet, which is to be submitted in court within a week, sources add.

The tapes reportedly have Singh’s conversations with around 35 people. The Special Cell had taken Singh’s voice samples when he was called in for questioning 10 days ago. These were then sent to the Hyderabad lab for voice-matching.

The Delhi Police claim that three detectives—Bhupendra Kumar, Vijay Dhawan and Anurag Singh—were involved in a conspiracy to tap Amar Singh’s phone for ‘‘monetary gain’’ and that no political mastermind was involved. While Bhupendra and Dhawan effected the tapping based on forged orders purportedly from the Centre, Anurag tried to sell the CD for money, the Delhi Police claim.
