Rajaratnam in the past has actively contributed to various Democratic candidates campaigns including those of Charles Schumer and Hillary Rodham Schumer and $87,000 to President Barack Obama’s campaign.

However, his largest contribution of $3.5 million was made to the Tamil Rehabilitation Organization, linked to the Tamil terrorist group LTTE and was later banned by the U.S. Treasury. He also donated to clear land mines in the war torn regions of Sri Lanka.

Authorities also charged three executives at Intel, Mckinsey & Company Inc and IBM.

Rajiv Goel, 51, an employee of the treasury department at Intel located in Los Gatos, California, Anil Kumar, 51, a director of McKinsey and Robert Moffat, 53, senior vice president at IBM.

Two others who worked at New Castle, the hedge fund group that once was operating under Bear Stearns Asset Management Inc were also charged.

Danielle Chiesi at New Castle who played a key role in providing information linked to Akamai and Sun Microsystems and president of New Castle Mark Kurland.

The regulators allege that Rajaratnam used the insider information obtained from the people charged to trade for the benefit of funds managed by Galleon that yielded $18 million of profits.

According to the charges, Chiesi obtained information from sources at Akamai Technologies and Goel provided insights into the restructuring at Advanced Micro Devices and from Moffat at IBM related to earnings.

The taped conversation transcripts released in the court filings show that Rajaratnam sought insider information from multiple sources that focused on short term results ahead of earnings release.

The prosecution built its case with the help of an unnamed informant who is hoping to get a lesser sentence.

According to a cooperating witness at the time of the interview for a job position at Galleon, Rajaratnam asked “if the Tipper A had inside information about any public companies.”

The cooperating witness known as Tipper A after a brief work history at Galleon in the late nineties sought to work again in 2005 with Rajaratnam and had known him since 1996.

Prosecutors allege that Galleon and others have benefited to tune of $12.7 million based on sources about information related to Polycom Inc, Google Inc and information related to the sale of Hilton Hotels Corp.

Galleon Group released a statement after the arrest that noted the following.

“Galleon was shocked to learn today that Raj Rajaratnam was arrested this morning at his apartment. We had no knowledge of the investigation before it was made public and we intend to cooperate fully with the relevant authorities. Galleon continues to operate and is highly liquid.”
