New Delhi, Mar 6: Former Indian Air Force (IAF) chief S.P. Tyagi's brothers were questioned by the Central Bureau of Investigation (CBI) here Wednesday on the alleged kickbacks in the $750 million (Rs.3,600 crore) deal for 12 VVIP helicopters.
CBI sources said S.P. Tyagi's brothers Julie and Docsa Tyagi were questioned at the CBI headquarters Wednesday.
"The Tyagi brothers were questioned for around eight hours in the chopper deal," the CBI official said.
Sources said the agency may question the former air chief Thursday.
The CBI had Tuesday questioned Aeromatrix CEO Praveen Bakshi, former union minister Santosh Bagrodia and lawyer Gautam Khaitan in the case.
A CBI and defence ministry team had gone to Italy last month to collect documents concerning alleged kickbacks to clinch the deal.
The investigative agency had filed a preliminary inquiry against 11 people Feb 25.
Besides S.P. Tyagi, the inquiry names his cousins Sanjeev alias Julie Tyagi, Docsa Tyagi, Sandeep Tyagi, Khaitan (who was formerly associated with Aeromatrix) and Bakshi.
Others named in the inquiry include Giuseppe Orsi, former CEO of Italian defence major Finmeccanica; Bruno Spagnolini, CEO of AgustaWestland, a Britain-based subsidiary of Finmeccanica; and alleged middlemen Guido Ralph Haschke, Karlo Valentino, Ferdinando Gerosa, and Christian Michel.
The firms named are Finmeccanica, AgustaWestland, IDS Infotech Ltd. (India) and Aeromatrix India.
