The Government Examiner for Questioned Documents is understood to have confirmed that Samajwadi Party general secretary Amar Singh's cell phone was tapped and that the voice samples recorded on the compact discs was from a phone belonging to him.

The GECD, which has examined the computer discs and CDs seized by the Delhi police in the Amar Singh phone-tapping case, submitted its interim report to the Delhi police on Tuesday, according to sources.

• Who tapped Amar Singh's phone?

However, the GECD, functioning under the Director of Forensic Science in the Union Ministry of Home Affairs, reportedly stated that there was nothing sensational and interesting in the recordings sent by the Delhi police.

The GECD experts heard a random sampling of conversations in 200 calls and found them to be routine.

No female voice was identified in the recordings. Most of the persons in the recording spoke in Hindi and English.

Since the material sent to the GECD did not contain all the recordings made while tapping Amar Singh's phones, the GECD informed the Delhi police that "we cannot conclude that there is nothing sensational in them".

It may be recalled that the Delhi police registered a case against three private detectives Bhupendra Kumar, Vijay Kumar Dhavan alias Vijay Grover and Anurag Singh in connection with Amar Singh phone-tapping case.

Besides the trio, Kuldeep Singh, an employee of Reliance [Get Quote] Infocomm, was arrested. CDs, mobile phones and other incriminating materials were seized from them.

PTI adds:

Meanwhile, forensic experts Wednesday said Samajwadi Party leader Amar Singh's 'voice test' in the phone tapping case was not complete as the entire material has not been made available to them.

"We are not in a position to say anything about the test as they are not yet complete and the full material did not arrive from Delhi," sources in the GEQD told PTI in Hyderabad.
