Two-time Golf Winner Angel Cabrera Arrested in Brazil

An unnamed 51-year-old Argentinian was arrested Friday in a statement from federal police in Rio de Janeiro.

A Rio de Janeiro federal police officer who does not want to be identified confirmed to CNN that the person arrested is "the famous golf champion El Pato."

Angel Cabrera, known as "El Pato," has won both the Masters and the US Open.

Police say Brazil's Supreme Court has issued an extradition warrant and the person will be sent to prison until final extradition back to Argentina.

Cabrera has been accused of assaulting his ex-girlfriend in Argentina and of theft.

CNN has spoken with its attorney, Miguel Gavier, who has promised a statement.

] In August, Gavier told CNN and Espanol that Cabrera has denied the charges. He said he does not understand why Interpol's red notice was issued for Argentina because his client is cooperating and that he has received a signed statement from the prosecution stating that it was not necessary for Cabrera to be allowed to travel.

Last year, the judge declared that in order to remain free, Cabrera had to maintain permanent residence in Argentina and make himself available to the Court after being summoned.

"He is innocent in both cases and expects to be acquitted based on the evidence gathered," he said.

Neither Interpol nor the Court of Justice in Cordoba, Argentina have answered CNN's calls.

Police say the arrest took place in a flat in Leblon, south of Rio de Janeiro. Cabrera has been charged in Argentina
