New Delhi, July 15 -- Robert Vadra, son-in-law of Congress leader Sonia Gandhi, on Monday appeared before the Enforcement Directorate (ED) for questioning in connection with the agency's probe against fugitive arms middleman Sanjay Bhandari, people familiar with the development said. The businessman husband of Congress member of Parliament Priyanka Gandhi Vadra reached the ED's office at APJ Abdul Kalam Road around 11am and was interrogated by a team regarding his association with Bhandari, a property in London linked to him and other related aspects of the case, officials said. He had earlier skipped ED summons on two occasions - June 10 and 17 - citing different reasons. ED's probe against Bhandari, in which Vadra is also under the scanner, relates to two properties in London as well as some land parcels in India. A Delhi court on July 5 declared Bhandari a fugitive economic offender, a tag which allows ED to attach his properties worth Rs.655 crore. As exclusively reported by HT on July 9, the financial crimes probe agency has identified 16 properties of Sanjay Bhandari (12 in Delhi and the National Capital Region, two each worth several million dollars in the UK and the United Arab Emirates) and bank deposits, jewellery and cash running into crores, which can now be confiscated because he was declared a fugitive economic offender (FEO)....
