RIO DE JANEIRO -- A Brazilian judge ordered Wednesday that the passports of American swimmers Ryan Lochte and Jimmy Feigen be seized, confining them to the country as authorities investigate their claim they were robbed at gunpoint during the Rio de Janeiro Olympics.
It was not immediately clear whether the swimmers were still in Brazil.
The office of Judge Keyla Blank confirmed the order Wednesday in a statement.
The U.S. Olympic Committee said police went to the athletes village Wednesday morning to try to collect the passports, but the swim team had already moved out. Spokesman Patrick Sandusky declined to say whether Lochte and Feigen were still in the country.
"As part of our standard security protocol, we do not make athlete travel plans public and therefore cannot confirm the athletes' current location," Sandusky said. "We will continue to cooperate with Brazilian authorities."
A USA Swimming spokesman and Lochte's attorney, Jeff Ostrow, did not immediately return messages seeking comment.
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.
Ostrow has said there is no question the robbery happened. Ostrow said Lochte had been staying in this hotel room and intended to go back to the U.S. soon.
According to statements from Lochte and the USOC, the swimmers were returning to the athletes village by taxi after a night out at the French Olympic team's hospitality house in the Rodrigo de Freitas area in the upscale south zone of the city.
Traveling with Lochte and Feigen were Gunnar Bentz and Jack Conger. Lochte swam in two events at the Rio Games, winning gold in the 4x200-meter freestyle relay. He is a 12-time Olympic medalist.
The group did not call police, authorities said, and officers began investigating once they saw media reports in which Lochte's mother spoke about the robbery. Police interviewed Lochte and one other swimmer, who said they had been intoxicated and could not remember what type and color of taxi they rode in or where the robbery happened, the police official said. The swimmers also could not say what time the events occurred.
Later in the day, Lochte described the incident to NBC's "Today" show .
"We got pulled over, in the taxi, and these guys came out with a badge, a police badge, no lights, no nothing just a police badge and they pulled us over," Lochte said. "They pulled out their guns, they told the other swimmers to get down on the ground - they got down on the ground. I refused, I was like we didn't do anything wrong, so - I'm not getting down on the ground.
"And then the guy pulled out his gun, he cocked it, put it to my forehead and he said, 'Get down,' and I put my hands up, I was like 'whatever.' He took our money, he took my wallet - he left my cellphone, he left my credentials."
Word of the robbery initially created confusion between Olympic and U.S. officials. An International Olympic Committee spokesman at first said reports of the robbery were "absolutely not true," then reversed himself, apologized and said he was relying on initial information from the USOC that was wrong.
Lochte told USA Today that he and his teammates didn't initially tell the U.S. Olympic officials about the robbery "because we were afraid we'd get in trouble."
