The Enforcement Directorate on Saturday denied that it searched the prermises of persons linked to Congress President Rahul Gandhi's brother-in-law Robert Vadra without an FIR or search warrant, saying its action was within "prescribed procedure".
"These searches have been carried out as per the prescribed procedure," it added.
The statement said that documents and digital evidence were seized during the searches and were being examined.
The ED has also questioned Manoj Arora, Ramesh Sharma and another person whose identity has not been not disclosed.
While being taken by the ED officials, Jagdish Sharma told reporters on Saturday: "Robert Vadra is being framed. The Modi government wants to trap him. Searches are on at my residence. What will they get when there is nothing? They are taking me to ED office for questioning."
The Congress termed the ED action as "blind vendetta" by the government to score political points.
According to the ED, the suspects are linked to the firms of Vadra and are linked to alleged commissions received by some suspects in defence deals. The agency refused to share details of the defence deals.
Vadra had earlier this week alleged that the corruption probe against him was the result of a political witch-hunt aimed at "besmirching his dignity and reputation".
