The government has already frozen the contract for supply of 12 AW-101 VVIP choppers to the IAF after allegations that Rs 360 crore were paid as bribe in which two top officials of the company were accused.
IAF has already received three helicopters and delivery of the rest has been put on hold.
Soon after the arrest of the firm's former CEO, Guiseppe Orsi, in Italy in connection with the case, Defence Minister A K Antony had suspended the payments to be made to it along with the delivery it was due to make to IAF for the remaining nine choppers.
