On Friday morning, searches were conducted in Delhi in connection with a money laundering investigation involving the city-minister, state's Satyendar Jain.
The agency under the PMLA is investigating Jain, a minister without portfolio in the Kejriwal government, on grounds of alleged hawala dealings.
The Enforcement Directorate searched over ten places around the national capital, according to news agency PTI.
His detention was prolonged by 14 days earlier this week.
After similar raids were undertaken against Jain's family and others following his arrest, the CBI claimed to have seized "unexplained" cash worth Rs 2.85 crore and 133 gold coins.
On Tuesday, a court in the capital postponed a decision on his bail application until Saturday. While the investigation agency claims Jain has been evasive during the investigation, his lawyer informed the court that he was complying.
Officials from the federal investigation agency are conducting searches at at least ten home and business locations.
On May 31, the AAP's leader was apprehended by the investigation agency. His detention became a major issue of contention between the BJP and the Aam Aadmi Party.
