The story told by four American swimmers about being robbed at gunpoint last weekend continues to unravel as various surveillance videos show a very different chain of events from what was originally reported.

A video from a security camera at a gas station shows one American swimmer breaking down the door to a bathroom and getting in a fight with a security guard.  Other videos show discrepancies in their stories as well.

ABC News:

As the police investigation continues into the alleged robbery of four U.S. Olympic swimmers in Rio, a Brazilian police source told ABC News that "one of the swimmers was seen on CCTV footage breaking down the door to the bathroom at [a] gas station and fighting with a security guard" on the night of the incident.

Police told ABC News that the swimmers "offered 100 reals and $20" to compensate for the damage.

Surveillance video from Brazil’s Globo TV shows the swimmers at a gas station.

Swimmer Ryan Lochte claimed on Sunday that he and three teammates were robbed in a taxi early that morning while heading to the Olympic Village in Rio de Janeiro.

Additional surveillance footage obtained by Globo TV shows the swimmers arriving at the French House party around 1:45 a.m. and leaving four hours later. According to the judge, the Olympic athletes claimed to have left the party at 4 a.m.

Lochte told NBC News' Matt Lauer Wednesday night that the swimmers used a restroom at a gas station and when they got back to their taxi, the driver didn't move. That's when two men approached with guns and badges and told them to get out and get down, Lochte said.

Lochte returned to the U.S. on Wednesday, but the three other swimmers — Jack Conger, Gunnar Bentz and James Feigen — remain in Brazil.

United States Olympic Committee spokesman Patrick Sandusky said Conger and Bentz were detained Wednesday night "shortly before their flight was scheduled to depart from Rio."

"They were released by local authorities, with the understanding that they would continue their discussions about the incident," he said.

Sandusky said Lochte's teammates "are cooperating with authorities and in the process of scheduling a time and place today to provide further statements to the Brazilian authorities."

It seems far more credible that the young men concocted the robbery story to cover up their vandalism and run-in with a security guard.

Lying to the police is a serious matter in any country, and the Brazilians may want to throw the book at the Americans because of the worldwide attention given the robbery story.  In truth, there are numerous reports by athletes and visitors of armed robberies during the games, so debunking one such report hardly seems worth the effort.
