Officials said the ED raided at least three locations in Faridabad near New Delhi.
They said the agency is looking at collecting and seizing important documents and other possible incriminating evidence in this case and hence, raids are being conducted on premises of two persons involved in the matter.
The ED had recently attached assets worth Rs 1.18 crore of government officials and others in connection with the case under the provisions of the Prevention of Money Laundering Act (PMLA).
The case pertains to a land in Kolayat area of Rajasthan's Bikaner district which was meant to be allotted to those displaced due to the army's Mahajan field firing range.
The ED had registered a criminal case under the PMLA in the matter in 2015 taking cognisance of FIRs filed by the state police after the local Tehsildar had complained of alleged forgery.
However, it did not mention the name of Vadra or any company linked to him in its FIR filed under the PMLA.
In the FIR, it had named some Rajasthan government officials and the "land mafia".
Mr Vadra had denied any wrongdoing even as the Congress had called the action "sheer political vendetta".
