Rajaratnam is accused of operating an elaborate insider trading operation through his Galleon Group hedge fund, which made him one of the wealthiest men in America with an estimated net worth of $1.3 billion.

The case against Rajaratnam and the five others indicted alleges they netted over $25 million in profits and marked the first time a court authorized wire taps were used in a hedge fund case.

A Sri Lankan native, Rajaratnam gave more than $3.5 million to the Tamil Rehabilitation Organization (TRO), whose assets were frozen by the U.S. Treasury Department in Nov. 2007 because of its alleged ties to the Tamil Tigers.

According to documents filed with the IRS, Rajaratnam's contributions to the TRO were made in 2005 and 2006 through a separate charity, which he founded in the wake of the tsunami which hit Sri Lanka in Dec. 2004Despite its stated relief efforts, the Treasury Department described the TRO charity as "a front" for Tamil Tigers fundraising and procurement in the United States.

"TRO passed off its operation as charitable, when in fact it was raising money for designated terrorist group responsible for heinous acts of terrorism," said Adam Szubin, director of the Treasury's Office of Foreign Assets Control at the timeThe Tamil Tigers waged a bloody insurgency against the government ofSri Lanka in which both sides were accused of civilian atrocities. Under the Clinton administration, the State Department designated the Tamil Tigers as a terrorist organization in 1997.

Sri Lankan government officials alleged that contributions funneled through U.S. and Canadian-based charities prolonged the group's bloody campaign.

The leader of the Tamil Tigers were killed by government forces in May, effectively putting an end to its insurgency.
