Former Union finance minister P Chidambaram's plea for anticipatory bail was turned down today by the Delhi High Court, opening up the possibility of his arrest in the INX Media case. The CBI visited his home this evening and left a notice, asking him to present himself at the agencys office within two hours of seeing it. Investigators say Mr Chidambaram facilitated a mammoth foreign funding for the television company in 2007, for which his son Karti Chidambaram received kickbacks. The court said prima facie, there's evidence that the former minister is the "kingpin" and blocking the investigative agencies will send a "wrong message". Mr Chidambaram has denied any wrongdoing.
