Congress leader P Chidambaram's son Karti Chidambaram's office in Chennai was raided by the Enforcement Directorate on Wednesday, 16 December following which he issued a statement denying any cause for concern.
"Neither I nor any of my family members have any connections with the said firms," said Karti, after the raids.
P Chidambaram, in a statement, has said, "Mr Karti Chidambaram has made a statement. As can be expected, nothing was found in the fishing and roving enquiry."
"I would like to see how far a foolish government will go in harrassing him. I still believe that the departments I left behind have many officers who will act according to law and their conscience," he added.
Previously, on 2 December, a team comprising both ED and Income Tax officials had raided firms Karti is associated with in Chennai. This was to do with alleged money laundering in the Aircel-Maxis telecom deal.
While there is no definitive word on why the raid on Karti's office occurred, the previous raids were conducted after the director of a company that Karti allegedly owns gave a tip off on important files at the Office of Chess Global Advisory Services Pvt Ltd.
A laptop that was recovered from Karti's office has been confiscated.
Karti, other than being a Congress leader himself, is also the chairman of India's only ATP tournament - Chennai Open.
