Raj Rajaratnam, the Galleon Group hedge-fund manager sentenced to 11 years in prison for masterminding an insider-trading scheme, made inaccurate statements about the federal investigation in an interview published in Newsweek magazine, US officials said.

“A number of his assertions are inaccurate,” said Ellen Davis, spokeswoman for Manhattan US Attorney Preet Bharara. Jim Margolin, a spokesman for the FBI in New York, said that comments Rajaratnam attributed to FBI agents “were never uttered.”
