The Enforcement Directorate on Tuesday recorded the statement of Karti Chidambaram in connection with the Aircel-Maxis deal case.
"The questioning is being done under the Prevention of Money Laundering Act at our Delhi office," said an official.
In January, the agency had conducted searches on the Chennai and Delhi premises linked to Mr. Karti in the same case.
On December 1 last year as well, the ED had searched the premises of a close relative of Mr. Karti and others. In September 2017, the agency attached assets worth Rs.1.16 crore of Mr. Karti and a company in the case.
Contesting the legality of the ongoing probe by the ED and the Central Bureau of Investigation, Mr. Karti and his father P. Chidambaram have, on several occasions, said that the charge sheet in the Aircel-Maxis case has already been quashed by the Special Court and all the accused discharged.
However, the agencies have maintained that the FIR in the case has not been quashed.
