New Delhi: The Supreme Court on Wednesday allowed Karti Chidambaram, son of former Finance Minister P Chidambaram, to travel abroad after depositing '10 crore as security but said it would "come down heavily" on him if he did not cooperate in the probe into the INX Media and Aircel Maxis cases. "Don't play around with the law," the apex court warned Karti.

Directing him to give an undertaking that he would abide by the conditions, the court asked Karti to appear before the Enforcement Directorate (ED) on March 5, 6, 7 and 12 for the questioning. "You (Karti) can go wherever you want to, you can do whatever you want, but don't play around with the law. If there is an iota of non-cooperation, we will come down heavily," a bench headed by Chief Justice Ranjan Gogoi said. "You go wherever you want to go, between February 10 and 26 but you must cooperate with the investigation. You had not been cooperating with investigations. We have lot to say but would not say for now," said the bench, which also comprised Justices Deepak Gupta and Sanjiv Khanna.
