The CBI is inching towards filing charge sheet in the VVIP helicopter deal as it has got almost all the documents from Italy which are now being studied.
CBI sources said they managed to get the complete tranche of records, received from Italy, translated into English.
They said the contents are being analysed by the investigators who would decide on the charges to be pressed against the accused named in the FIR that includes former Chief of Air Staff S P Tyagi and his three cousins.
CBI had named 13 individuals, including Tyagi and European middlemen Carlo Gerosa, Christian Michel and Guido Haschke, in the FIR as accused, in connection with the alleged bribery.
Italian agencies had arrested the then CEO of AgustaWestland Giuseppe Orsi for alleged bribe given to Indian middlemen to clinch the deal.
The supply of 12 VVIP helicopters from AgustaWestland had come under scanner after Italian authorities alleged that bribe money was given by the company to clinch the deal.
The Italian prosecutor, who carried out the preliminary enquiry, alleged that the CEO of Finmeccanica, parent company of UK-based AgustaWestland, had used services of middlemen to bribe Indian officials.
The probe agency has alleged that during his tenure as IAF chief, Tyagi and "with his approval" the Air Force "conceded to reduce the service ceiling for VVIP helicopters from 6,000 m to 4,500 m as mandatory to which it was opposing vehemently on the grounds of security constraints and other related reasons".
"Haschke Guido and Gerosa Carlo (middlemen) managed to send Euro 5.6 million through Mohali-based IDS Infotech and Chandigarh-based Aeromatrix Info Solutions Private Ltd to India and kept the remaining amount out of about Euro 24.30 million received from AgustaWestland with themselves in the account of IDS Tunisia," FIR said.
Both the Indian companies have denied involvement in the bribery scandal.
