The Enforcement Directorate (ED) on Monday, 6 June, searched the residence of Delhi's Health and Home Minister Satyendar Jain in connection with alleged hawala transactions related to a Kolkata-based company.
The raids are being conducted as part of a "follow up" in the case, officials told news agency PTI.
Jain, who holds health, power, and home portfolios, was on Monday arrested by the Enforcement Directorate in a case related to money laundering. The portfolios allocated to Jain were handed over to Sisodia on Thursday.
A special court had last week granted ED custody of the Aam Aadmi Party (AAP) leader till 9 June.
The agency, in April this year, provisionally attached immovable properties worth Rs 4.81 crore belonging to companies allegedly linked to Jain and his relatives under the Prevention of Money Laundering Act (PMLA), 2002.
