A few people in the power corridors might have heard about Rajiv Tyagi, a doctor who has been named as one of the alleged beneficiaries in the Rs 3,600 crore VVIP helicopter deal with Italy. An old friend of Tyagi said he used to know the doctor when he was handling the election of Bollywood superstar Amitabh Bachchan from Allahabad between 1984 and 1989. “After 1989, I only heard stories about his prosperity that he had bought a house in Sainik Farms and another in the west-end areas of Delhi,” said the senior National Democratic Alliance leader.
