CCTV showing American swimmers Ryan Lochte, Jimmy Feigen, Jack Conger, and Gunnar Bentz returning home to the Olympic Village early on Sunday morning has deepened the mystery surrounding the alleged robbery they suffered.
Lochte and Feigen gave a statement to police earlier this week, claiming they left the club they were in at about 4 am and took a taxi straight from the club to the village - a journey of around 30 to 40 minutes. The robbery reportedly happened along the way.
However the CCTV footage shows the time of their return to the Village at 0656, nearly three hours after they claim to have left the club.
The alleged robbery is already the subject of a police investigation in Brazil, and a judge in Rio has ordered the four men to surrender their passports as the authorities probe a case which appears more complex with each passing day.
After Lochte's mother broke news of the alleged robbery on social media and in media interview, Lochte gave his own interview to NBC. The Brazilian police claim he did not inform them before going to the broadcaster.
"We got pulled over, in the taxi," Lochte told NBC. "These guys came out with a badge, a police badge, no lights, no nothing, just a police badge and they pulled us over. They pulled out their guns, they told the other swimmers to get down on the ground. They got down on the ground. I refused.
"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."
When the police launched their own investigation, an official told the Associated Press that Lochte and Feigen were unable to give basic details and contradicted each other's stories.
The four athletes were then ordered to surrender their passports. However, by the time the order was made, Lochte had already landed in the US. Conger and Bentz were pulled off a flight to be questioned by police, while Feigen is still believed to be in Brazil.
Lawyers say they won't be able to leave the country until they are interviewed, and the investigation continues.
