Robert Vadra's lawyer KTS Tulsi ensured in court that Vadra will join the Enforcement Directorate (ED) investigation on February 6.
The case relates to allegations of money laundering in the purchase of a London-based property located at 12, Bryanston Square, worth 1.9 million pounds, which is allegedly owned by Vadra, the brother-in-law of Congress President Rahul Gandhi.
The ED lodged a money laundering case against Vadra's close aide Manoj Arora after his role surfaced during the probe of another case by the Income Tax Department under the new Black Money Act and tax law against absconding arms dealer Sanjay Bhandari.
It said that the London-based property was bought by Bhandari and sold in 2010 for the same amount despite incurring additional expenses on its renovation.
On December 7, as part of its investigation, the ED conducted searches at a number of premises in Delhi-NCR and Bengaluru.
Refusing to speak on a sub-judice matter, Robert Vadra, Congress President Rahul Gandhi's brother-in-law, had previously asserted that he is not scared and is not running away from the country because he knows that he's not wrong.
On December 7, the ED carried out searches at the premises of people linked to Vadra in Delhi, National Capital Region and Bengaluru in connection with some defence deals. It also questioned four people, including a Congress worker and two of Vadra's employees, in this connection.
The Congress has attacked the Narendra Modi government over the raids, accusing that the prime minister was misusing the probe agencies.
