Gas station owner: Lochte, teammates urinated everywhere

Errant urination at a Rio gas station led to the confrontation U.S. swimmer Ryan Lochte later described as a robbery at gunpoint, the gas station owner told Brazilian newspaper O Globo's Guilherme Ramalho.

The owner claims Lochte and teammates James Feigen, Gunnar Bentz, and Jack Conger urinated on a wall at the station and also committed at least one other act of vandalism, tearing down a poster.

"They stopped at the side of the station and urinated all over the side," the owner said, as translated by theScore. "I still have the image of one of their behinds, dropping their pants. They were told to go to the bathroom, but they urinated on the wall on the side. They didn't respect the sign, they didn't go to the bathroom," said the owner, who preferred to not be identified.

The Olympians were apparently returning to their accommodations in Rio in a taxi after a night of partying.

Brazilian police say they have video showing one of the swimmers damaging a bathroom door and fighting with a security guard, according to multiple reports.

Lochte initially claimed he and his teammates were robbed at gunpoint by thieves posing as police officers, but has since changed elements of his story.

The story is fabricated, Brazilian sources told ABC News' Matt Gutman.
