New Delhi, Feb 27 (IANS): After initiating preliminary inquiry into the alleged kickbacks in the $750 million/Rs.3,600-crore deal for purchase of 12 VVIP helicopters, the CBI Tuesday analysed some fresh documents received from Italy and planned to question former Indian Air Force chief S.P. Tyagi and 10 others.

Central Bureau of Investigation (CBI) sources said its officials analysed some more fresh documents that its team brought to India from Italy.

Officials said the agency's legal department, whose member had gone to Italy, is likely to be made a part of the probe team looking into the helicopter deal with Britain-based AgustaWestland.

They said the agency is likely to seek more documents about India based companies and also to examine the individuals named in its preliminary enquiry.

The helicopter deal is likely to be discussed in the Rajya Sabha Wednesday.

Besides Tyagi, the inquiry names his cousins Sanjeev alias 'Julie' Tyagi, Docsa Tyagi, Sandeep Tyagi, advocate Gautam Khaitan, formerly associated with Aeromatrix, and the company's CEO Praveen Bakshi.

Others named in the inquiry include Giuseppe Orsi, the former CEO of Italian defence major Finmeccanica, Bruno Spagnolini, CEO of AgustaWestland - a Britain-based subsidiary of Finmeccanica - and alleged middlemen Guido Ralph Haschke, Karlo Valentino, Ferdinando Gerosa, and Christian Michel.

The firms named are Finmeccanica, AgustaWestland, IDS Infotech Ltd. (India) and Aeromatrix India.

Tyagi has categorically denied any involvement in influencing the VVIP helicopters deal in favour of AgustaWestland. Sanjeev Tyagi had also termed allegations of involvement of his family in the kickbacks as "hundred percent wrong and baseless".

Bakshi, too, has rubbished claims that the firm had anything to do with the alleged kickbacks in the deal.
