Chennai/New Delhi: The Enforcement Directorate (ED) on Wednesday conducted raids in Chennai at the premises of firms allegedly connected to former finance minister P. Chidambaram's son Karti.

Karti said neither he nor his family were shareholders in any of the firms, while Chidambaram issued a statement saying "nothing was found in the fishing and roving enquiry" and he would like to see how far a "foolish government" will go in "harassing" his son.
