"A detailed questioning on financial transactions conducted by the Organising Committee was done in Tihar jail today. Further questioning and recording of statement will happen soon," ED sources said.
The questioning lasted for more than two hours at the Jail Superintendent's office in the Tihar jail complex.
The agency, on June 3, had recorded a preliminary statement of Kalmadi under the provisions of the Prevention of the Money Laundering Act (PMLA).
The ED had then also briefly recorded the statements of two other officials, OC Joint Director General (Sport) A S V Prasad and Deputy Director General (Procurement) Surjit Lal who are also lodged in the jail.
Today''s questioning revolved around the financial dealings that were done by the OC under Kalmadi. The ED has registered about five different cases of money laundering in the conduct of the Games that were organised here last year.
The CBI, in its chargesheet against Kalmadi had described him as the "main accused" in a corruption case relating to irregularities in awarding the Time Scoring Results (TSR) contract to a Swiss firm.
"Kalmadi is the main accused as he was the person with all supreme powers. He had the supreme over riding powers in the Organising Committee of the CWG, 2010," the CBI charge sheet had said.
Kalmadi was arrested by CBI on Apr 25.
