A prosecutor's letter revealed by a US district judge has alleged that a second "insider at Goldman Sachs" may have passed tips to Raj Rajaratnam, the fund manager found guilty of insider trading. Bloomberg quoted US District Judge Jed Rakoff's summary of the prosecutor's letter in Manhattan, when he referred to "certain witness statements related to an insider at Goldman Sachs" who leaked tips that "did not relate to Goldman and or Proctor & Gamble." The comment was made during the indictment of Rajat Gupta, a former Goldman Sachs and Proctor & Gamble director due to stand trial on May 21 for leaking tips to Rajaratnam.
