New Delhi, Nov 28 (IANS): Solicitor General Tushar Mehta Thursday said the Enforcement Directorate is waiting to arrest Karti Chidambaram, son of senior Congress leader P. Chidambaram, who was also present in the courtroom during the hearing on the bail application of his father.

Mehta arguing before a three-judge bench headed by Justice R. Banumathi said the investigating agency is waiting for lifting of Delhi High Court stay on the arrest of Karti. He insisted that Karti has challenged few provisions of Prevention of Money Laundering Act in Delhi High Court.

Karti was expressionless during this argument, and instead he was looking at the judges on the bench.

Mehta reiterated before the court a stay has been imposed on his arrest by the High Court, and once it is lifted then he would also be arrested in the case.

Mehta was arguing against bail to P. Chidambaram before the apex court, and during the course of the argument he explained that a complex design was adopted to stop tracing of laundered money.

Senior advocate Kapil Sibal, appearing for Chidambaram, contested this ED's argument that he has been unfairly kept in judicial custody for nearly 100 days because he is the father of Karti, who is a key accused in the case.

Chidambaram was arrested by the CBI on August 21 in the INX Media corruption case and on October 22 he was granted bail by the top court.
