Former Goldman Sachs Director Rajat Gupta, a prominent Indian-Americans today surrendered before the FBI in New York in the case of insider trading scam. An FBI official told PTI that Gupta has surrendered to the Manhattan office of the FBI in New York. He said the charges against the 62-year-old Gupta are expected to be filed later in the day.

Gupta, a former director of Goldman Sachs and Procter & Gamble and head of McKinsey & Company, came under the scanner after prosecutors charged his Sri Lanka born hedge fund billionaire friend Raj Rajaratnam on insider trading charges. Rajaratnam had been sentenced to 11 years in prison earlier this month.

Gupta's lawyer, Gary Naftalis said in a statement that his client is innocent saying Gupta did not trade in any securities and did not tip Rajaratnam.

Securities laws prohibit company insiders from divulging corporate secrets to those who then profit from them.

A native of Kolkata, Gupta had a meteoric rise to corporate success after he graduated from Harvard Business School.
