RIO DE JANEIRO — A Brazilian judge has ordered that the passports of American swimmers Ryan Lochte and James Feigen be seized as authorities investigate their claim they were robbed at gunpoint during the Rio de Janeiro Olympic Games.



The office of Judge Keyla Blank confirmed the request Wednesday in a statement, but Rio police did not say whether the order was carried out.



Lochte and three of his teammates say they were robbed at gunpoint in a taxi Sunday morning as they returned to the athletes village from a party, several hours after the last Olympic swimming events were held.



Police have found little evidence so far to support their accounts, and say the swimmers were unable to provide key details in police interviews.



A police official with knowledge of the investigation told The Associated Press that police cannot find their taxi driver or witnesses. The official spoke on condition of anonymity because the investigation is ongoing. Lochte's attorney, Jeff Ostrow, has said there is no question the robbery happened.
