Karti Chidambaram said that the team was investigating three firms, of which two belong to his friends.
The office of Karti Chidambaram, son of former finance minister P Chidambaram, was searched today in Chennai by the Enforcement Directorate, which is investigating allegations of money-laundering linked to the 2G spectrum case.
"Some officers of the investigating agencies visited my office today," confirmed Karti Chidambaram in a press statement.
He said that the team was investigating three firms, of which two belong to his friends.
Stating that he was not aware of the third firm, Mr Chidambaram said: "I made it clear to the officers what I had publicly stated earlier. Neither I nor any member of my family is a shareholder or director in any of these said firms. We do not have any economic interest in the said firms."
He said nothing related to the companies were found in his office or taken from there.
"As far as I am concerned, I maintain that there was, and is, no basis for them to have visited my office or to make inquiries in my office," he said.
Following the search, P Chidambaram said, "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 harassing him (Karti)."
Earlier this month, the Enforcement Directorate and the Income Tax department raided Advantage Strategic Consulting, a company with which Karti Chidambaram was associated earlier.
In August, two directors of the company were summoned in connection with the Aircel-Maxis case and charges of money laundering.
Sources said there was allegedly a financial transaction of more than Rs. 200 crore between these two companies and Aircel Maxis just before the Foreign Investment Promotion Board cleared the Aircel merger.
The case is under scrutiny as part of the overall probe into the 2G scam, which the Supreme Court is monitoring.
