Unitech, had tanked 17.86 per cent yesterday, after the CBI removed a public prosecutor from the 2G spectrum case to verify his alleged discussions on prosecution strategy with the realty firm's MD and an accused in the case, Sanjay Chandra, in a taped conversation

Meanwhile, the CBI has taken voice samples of sacked public prosecutor A K Singh and Managing Director of Unitech Sanjay Chandra for identification.

The tapes purportedly containing voice of Singh and Chandra had been sent for forensic examination, CBI officials said, adding that the voice samples of the two had also been taken but would be handed over only after the examination of the tapes was completed.

Unitech had, however, issued a statement rejecting the allegations saying Chandra has never met the prosecutor in the 2G case outside the court or had any phone conversation with him.

Unitech also 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 company's statement had said.
