RIO DE JANEIRO (Reuters) - Brazilian prosecutors said on Friday they were seeking a heavier fine for U.S. Olympic gold medalist swimmer Jimmy Feigen for giving false testimony to police, after he had paid 35,000 reais to a charity as ordered by a Rio de Janeiro judge.

A court spokeswoman said that Feigen had made the payment to a Rio sports charity and could now collect his passport from police and leave the country if he wished to do so.

A spokesman for prosecutors said the request for a heavier penalty would not prevent Feigen from flying out of Brazil. He is the last of four U.S. swimmers involved in a scandal over fabricating a story about a robbery who still remains in Brazil.
