New Delhi:  Probing Gen V K Singh's complaint of alleged bribery offer made to him, the CBI will go through call records of retired Lt Gen Tejinder Singh to find out whether he was in touch with Vectra Chairman Ravinder Rishi or his associates before or after meeting the Army Chief.

CBI sources said the Army chief in his recent meeting with sleuths has assured them that he would provide some "clinching" evidence to buttress his complaint that Tejinder Singh had allegedly offered him a bribe of Rs 14 crore to clear supply of a tranche of all-terrain vehicles to the Army.

The CBI has met Army Chief on Friday last week to seek clarifications on his complaint but it is yet to meet Lt Gen (Retd) Tejinder Singh.

The agency, which has registered a preliminary enquiry in connection with complaint submitted by the Army Chief, is relying on three documents -- visitor's register, Record of Discussion of Army and documents related to Tatra, they said.

The sources said analysis of call records would give a clear picture about the allegations levelled by Gen Singh in his complaint. Tejinder Singh had refuted the allegations against him and even filed a defamation case against the Army Chief and other senior officers.

They claimed entries in the visitor's register show that Tejinder Singh did visit Gen Singh at his office on September 22, 2010 while the former had said that meeting was for personal reasons.

The Record of Discussion is an official document in which senior officials like Army Chief \ document communications, instructions, deliberations and decisions taken during a meeting, they said.

In his recent meeting with CBI officials, Gen Singh has reportedly told them that he would be providing them with a copy of the Record of Discussion of the day, on which he was allegedly offered bribe, in which he had recorded the deliberations between him and Lt Gen (Retd) Tejinder Singh and also the alleged bribe offer made to him.

The Army Chief had claimed in media interviews that an equipment lobbyist had offered him a bribe of Rs 14 crore, a matter which he had reported to Defence Minister A K Antony. The Ministry had then recommended a CBI probe into the allegation made by the Army chief.

Later in his complaint to the CBI, Gen Singh had alleged that it was Lt Gen (Retd) Tejinder Singh who offered him bribe on behalf of Vectra Chairman Ravinder Rishi.

Tejinder Singh, a former director general of Defence Intelligence Agency, had filed defamation complaint against the Army chief and four other Army officials trashing the allegations that he had offered the bribe for clearing a deal for 600 "sub-standard" vehicles.

Besides the Army Chief, he has named Vice Chief of Army Staff S K Singh, Lt Gen B S Thakur (DG MI), Major General S L Narshiman (Additional Director General of Public Information) and Lt Col Hitten Sawhney posted in the media cell, accusing them of misusing their official positions, power and authority to level false charges against him.

Tejinder Singh had contended that all the five formed a direct chain of command with the Army chief being the final arbiter. The Army Chief had in response to the legal notice by Tejinder Singh told him that he was ready to substantiate the allegations in the court.
