New Delhi: A key CBI witness and former aide of A Raja was on Tuesday put to hard questioning in a Delhi court during his cross examination by DMK MP Kanimozhi's lawyer Ram Jethmalani in the 2G scam trial.

Aseervartham Achary, former additional private secretary of Raja, was not only accused by Jethmalani of deposing falsely but was also asked as to how he got an expensive mobile handset.

"I do not know the approximate price of a handset of that brand (CLR). I do not know if the price of this brand is between Rs 2 lakh and Rs 4.5 lack," Achary said when Jethmalani asked him about the price of his mobile handset.

He said he did not knew the exact price of the handset as it was sent to him by one of his relatives, who resides in London, and denied that he had evaded any custom duty on it.

Jethmalani suggested to Achary that he was falsely deposing before the court that the former telecom minister had told him that then telecom secretary D S Mathur was not listening to him.

Achary answered this query saying, "...I could take the liberty with the minister (Raja) to ask such question because of my long association with him."

Jethmalani started questioning Achary before Special CBI Judge O P Saini asking whether he met the public prosecutor in his office for about one and half hours after on Monday's court proceedings were over.

The witness accepted that he had met CBI public prosecutor A K Singh for about five minutes but said he had gone to his office to ask as to at what time he had to come to the court today for the recording of his testimony.

To this, Jethmalani said, "I suggest you that you roughly took one and half hours at the public prosecutor's office and you were discussing your statement. As the court concluded the hearing around 1 pm on Monday, it was openly said that next day (on Tuesday), we will met at 10.30 am. Why did you go to the public prosecutor to ask this?"

The lawyer also asked Achary that before coming to the court on Monday, he had gone to the CBI headquarters and was accompanied to the court by a official of the agency.

Achary denied this but said that before entering to the courtroom on Monday, he had gone to the public prosecutor's office which is situated near the special courtroom.
