After carrying out its preliminary enquiry for nearly 16 days, the agency gathered evidence to register a case in connection with alleged payment of Ra 362 crore bribe to swing the 12 helicopter deal in favour of AgustaWestland, CBI sources said.
They said the agency has got some documents from Italy and files from the Defence Ministry which indicate criminal conspiracy to make alterations in the requirement of helicopter specifications which suited AgustaWestland.
The agency has also carried out detailed questioning of Tyagi, his cousins—Julie, Docsa and Sandeep, Gautam Khaitan, Praveen Bakshi and Bagrodia—last week, the sources said. All the accused have denied allegations against them.
