Actress Uma Thurman's money sense is being credited with helping to take down a Manhattan money manager who was arrested last week on charges of running a $30 million Ponzi scheme, the New York Post reports.

Kenneth I. Starr, who had managed money for stars including Wesley Snipes, Sylvester Stallone and photographer Annie Leibovitz, was arrested Thursday and faces federal charges of fraud and money laundering, the New York Times reported last week. He is not related to the special prosecutor who investigated former President Bill Clinton.

The criminal complaint does not identify victims by name, but lists one -- "Client 2" -- as an actress and close friend of Starr who'd been a client for more than a decade, the Times said.

Sources told the New York Post that the actress was Thurman. Reps for Thurman had not commented.

The complaint says the unnamed actress first noticed late last year that $1 million was missing from her account. She pressed Starr for months about the missing money, and it eventually returned to her account -- when Starr replaced it with money from other clients' accounts, federal prosecutors say.

In recent weeks, Thurman's story spread fast among Starr's other celebrity clients, the Post sources said. The news prompted at least one of them, "When Harry Met Sally" director Nora Ephron, to take her money out of Starr's firm, the Post said.

Ephron had not commented on the case.

In a statement, Leibovitz said she had not been a Starr client "for some time," adding: "News of Ken Starr's arrest does not come as a complete surprise to me, and I will follow this story with great interest."
