The premier investigation agency on Tuesday moved an application in the Special CBI court and sought permission to conduct narco analysis test, or lie-detector test, on Karti.
He is accused of receiving kickbacks a decade back to clear foreign investment into INX Media group, using the influence of his father P. Chidambaram, who was then the Union finance minister.
The Special CBI court on March 9 will hear arguments on Karti's bail plea, his narco test, and on production warrant requests.
The Enforcement Directorate (ED) had arrested S Bhaskararaman from a hotel in Delhi on February 16 in connection with the INX Media money laundering case.
On Sunday, the CBI took Karti to Byculla prison where he and Indrani were put face-to- face and questioned. (ANI)
