The ED, it is understood, wants to grill Vadra about the operations of a firm -- Ms Skylight Hospitality Private Limited -- allegedly linked to him, which had purchased land in the area.
The Rajasthan government had, in January 2015, cancelled the mutations (transfer of land) of 374.44 hectares of land, after the land department claimed to have found that the allotments were made in the names of "illegal private persons".
The Enforcement Directorate has issued a notice to a firm linked to Robert Vadra, son-in-law of Congress President Sonia Gandhi, in connection with its probe into alleged money laundering in a land deal in Rajasthan's Bikaner district.
The ED said the firm, Ms Skylight Hospitality, has been given two weeks time to furnish financial statements and other documents of the firm to the investigating officer of the case.
