The Central Bureau of Investigation (CBI) Monday registered a preliminary enquiry against 11 people, including former chief of air staff S.P. Tyagi, and four companies in the $750 million deal for purchase of 12 VVIP helicopters from AgustaWestland.
Apart from Tyagi, the enquiry names 'Julie' Tyagi, Docsa Tyagi, Sandeep Tyagi, Gautam Khaitan and Praveen Bakshi.
Others named include Giuseppe Orsi, the former CEO of Italian defence major Finmeccanica, Bruno Spagnolini, CEO of AgustaWestland - a Britain-based subsidiary of Finmeccanica, and Guido Ralph Haschke, Karlo Valentino, Ferdinando Gerosa, and Christian Michel.
The firms named are Finmeccanica, AgustaWestland, IDS Infotech Ltd. (India) and Aeromatrix India.
A CBI and defence ministry team had gone to Italy last week to collect documents concerning the controversial deal.
