NEW DELHI: After his arrest, P Chidambaram was taken to the CBI headquarters in Lodhi Colony, where he was placed under arrest. In the vehicle on way to the CBI HQ, he was made to sit between two policemen — a protocol followed by law-enforcement agencies to prevent an accused from hurting himself or fleeing.Chidambaram will be produced before a court on Thursday noon. Sources said the agency may also ask his son, Karti, to join the investigations so that they can bring the duo face-to-face and cross-examine them. CBI had registered an FIR alleging irregularities in the Foreign Investment Promotion Board (FIPB) clearance given to INX Media for receiving funds from abroad to the tune of Rs 305 crore in 2007. At the time, Chidambaram was the finance minister.The allegations are that Karti used his father’s position in the UPA government to facilitate the FIPB clearance for INX Media which was then owned by Indrani and Peter Mukerjea, currently in jail in connection with the Sheena Bora murder case. In February 2018, Karti Chidambaram was arrested in the case and had to remain jail for over twenty days before getting bail. His CA S Bhaskararaman was also arrested around that time. Chidambaram’s arrest had looked imminent since Tuesday after CBI and ED opposed his anticipatory bail plea saying his custodial interrogation was required because he was being evasive during questioning.
