The CBI today moved a New Delhi court seeking permission to conduct a narco analysis test on Karti Chidambaram in the INX media case. Special judge Sunil Rana said that the court would take the matter on March 9 along with two other applications seeking production warrants of Karti Chidambaram's chartered accountant S Bhaskaraman, arrested in the money laundering case, and co-accused Indrani Mukerjea. Karti Chidambaram was yesterday sent to three more days of the Central Bureau of Investigation custody with the court saying that the extension of his remand was necessary to maintain continuity in the investigation to secure evidence to arrive at the truth. -- PTI
