Police in Rio say they’ve found no evidence supporting Ryan Lochte‘s claim that he and three other swimmers were robbed at gunpoint while in the Brazil for the 2016 Olympic Games, according to the Associated Press.
The 32-year-old Olympian told NBC that he and his fellow athletes were held up after robbers posing as police officers pulled them over in a taxi. But police have not been able to find their taxi driver or witnesses, and they say the swimmers were unable to provide key details in police interviews, the AP reports.
The United States Olympic Committee confirmed the incident in a statement and two sources with the U.S. Team confirmed to PEOPLE that Lochte was robbed, but had no additional details.
“Everything’s up in the air now,” the source said. “But we know that something happened last night and that it really shook Ryan up.”
Lochte’s lawyer, Jeff Ostrow, told the AP that there was no doubt that the robbery happened and Lochte hadn’t been leaving his hotel room since.
“This happened the way he described it,” Ostrow said. “Ryan was a hundred percent cooperative and fully available when they reached out to us for an interview.”
He added: “It doesn’t behoove Ryan and anyone else to make up a story.”
Ostrow did not immediately return a call from PEOPLE seeking comment.
Days after the alleged robbery, Lochte spoke out about the incident on NBC News.
“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.”
He continued: “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 cell phone, he left my credentials.”
Lochte told USA Today Sports on Tuesday that he and the other swimmers did not initially tell the USOC about the incident “because we were afraid we’d get in trouble.”
