"A friend of mine is the auditor of that television company and it is the only connection I have with that firm," he said referring to the CBI naming him as an accused in the INX media case.
Karti, who is now in London, said in a Facebook post that CBI had "unnecessarily" included his name in the case.
On May 15, CBI had filed an FIR against Karti, Indrani and Peter Mukerjea on charges of criminal conspiracy, cheating, receiving illegal gratification, influencing public servants and criminal misconduct.
Yesterday, the Enforcement Directorate had registered a money laundering case against Karti and INX Media for alleged irregularities in the Foreign Investment Promotion Board's (FIPB) approval for the company to get Foreign Direct Investment.

Karti, who posted a facsimile image of his interview to a Tamil media outlet, said though this was a "corruption case, there are no details about which government official was bribed, they have just mentioned some unknown officials."
"Only if they had got anything, could they be able to spell that out," he said, apparently claiming that no seizure of evidential value was made.
Karti also said that he had not received any summons from CBI to appear before it in Delhi.
He also uploaded a photo of his with Richard Evans, eminent historian and president of Wolfson College, University of Cambridge.
