New York Times – Roomy Khan, the central witness who brought down the Galleon hedge fund, is a former Galleon employee with a history of financial trouble who agreed to cooperate with prosecutors after she was caught making trades using inside information.
Ms. Khan, previously identified only as “Tipper A” or a cooperating witness, provided much of the evidence that prosecutors are using to bring insider trading charges against the billionaire Raj Rajaratnam, who is shutting down his Galleon fund in the wake of the charges.
