The Central Bureau of Investigation (CBI) has sought permission from the court to conduct a narco analysis test on Karti Chidambaram. Allegedly, the decision was made as Karti had been evading questions posed by the CBI. According to reports, the only answer he gives is that the case is motivated politically. The narco analysis test would involve administering sodium pentothal into Karti so as to lower his inhibitions and induce free talking. Reportedly, the agency will move the application in the court on March 9.
