Karti Chidambaram, the son of former union minister P Chidambaram, has been sent to CBI custody for a day by a court in Delhi. The 46-year-old businessman was arrested this morning in Chennai and then brought to Delhi. He has been accused of taking bribes to help a television company, INX Media, get clearance for foreign investments. Sources said the CBI suspects that he received Rs. 3.5 crore through a company linked to him and a fresh case will be filed against him. While he was being taken to court, Karti Chidambaram told reporters, "This is vendetta, I will be vindicated".
