New York: The lawyer for Raj Rajaratnam, main accused in the largest hedge fund insider trading case in US history, on Friday denied allegations that former Goldman Sachs Inc director Rajat Gupta passed insider tips to Galleon Group founder Rajaratnam.

John Dowd, Rajaratnam's lawyer, asked the jury why Gupta, 62, would risk his entire career and reputation for nothing.

"Rajat Gupta did not receive anything. Rajaratnam did not give him anything," Dowd said.

During the rebuttal, US Attorney Jonathan Streeter said out that Gupta was an investor in Galleon's GB Voyager Multi-Strategy Fund, a fund that included assets from other Galleon funds.

"He stood to benefit if Raj makes more money," he said.

Streeter told the jury that Judge Richard Holwell in his legal directions would tell them that benefits do not always have to be tangible but could also include making useful contacts or a favour returned down the road. Rajaratnam, 53, who has been charged with 14 counts of securities fraud and conspiracy, has maintained his denial of wrongdoing.

If convicted, he faces up to 20 years in prison. Out of the 26 people arrested in the case, 19 have pleaded guilty.

Gupta, has not been charged in the criminal case but faces civil charges from the US Securities and Exchange Commission for allegedly passing confidential information about Goldman Sachs to the defendant.

The government rebuttal in the hearing will continue on coming Monday.
