The Enforcement Directorate (ED) on Saturday grilled Rose Valley group chairman Gautam Kundu at Presidency Jail, where he is now lodged after his arrest around three and-a-half months back.
ED sources termed the interrgoation as routine.
"This was a routine investigation and was carried out as planned," a source told IANS but refused to give any more details about the grilling.
"Questioning is done to get more information and was done accordingly," the sources said.
Kundu was arrested on March 25 by the ED after he failed to give proper answers during sustained questioning spread over several hours on being summoned to its office.
The investigating agency has already filed a charge sheet against six officials of Rose Valley including Kundu under provisions of the Prevention of Money Laundering Act in pursuance of a complaint from the Securities and Exchange Board of India (SEBI).
