New Delhi, Mar 13: The Central Bureau of Investigation (CBI) on Wednesday registered a First Information Report (FIR) against 12 people, including former Air Force chief SP Tyagi, in connection to the AugustaWestland chopper deal case.
SP Tyagi's cousins, Julie Tyagi and Dosca Tyagi, and four firms have been named in the FIR.
According to reports, the CBI registered the FIR under sections 120 and 420 of the Indian Penal Code (IPC) and certain sections of Prevention of Corruption Act.
The CBI also conducted searches at 14 places in Delhi, National Capital Region (NCR) and Chandigarh in connection to the scam.
The CBI last week questioned SP Tyagi and his cousins in connection to the case.
Earlier, British Prime Minister David Cameron had assured Indian Prime Minister Manmohan Singh cooperation in the AugustaWestland chopper scandal.
Both Singh and Cameron discussed the issue during their meeting in New Delhi on Feb 19.
The Indian PM said he conveyed to Cameron the very serious concerns regarding allegations about unethical means used in securing the 2010 contract for Agusta Westland helicopters.
The Italian prosecutors, who named SP Tyagi as a part of the alleged payment of kickbacks in the Rs 3600 crore purchase deal of VVIP choppers by India from Anglo-Italian helicopter company AugustaWestland, earlier said they have enough evidence against Tyagi for framing the charges.
There are allegations of kickbacks worth 50 million euros in the scam, according to media reports.
