Brazilian police sources have reportedly told ABC News the U.S. Olympic swimmers who claimed they were robbed in Rio over the weekend may have fabricated their story. The source told a reporter that “one of the swimmers was seen on CCTV footage breaking down the door to the bathroom at the gas station and fighting with a security guard” on the night of the alleged crime. Ryan Lochte said Sunday that he and three teammates were held at gunpoint in a taxi at around 4 a.m. He then told Matt Lauer on Wednesday that the men used a restroom at the gas station and that the driver held the car still while men approached with weapons and badges. The gas station owner told a Brazilian newspaper that the swimmers committed vandalism at the establishment, including throwing stones at the building and then tearing off one of its signs. "They stopped next to the gas station, and urinated outside right next to the gas station. We even have images of one of the athlete's butts, as he is pulling up his pants," the owner reportedly said. Lochte left Rio on Tuesday, just before an order was issued for him to remain in Brazil. Other swimmers were pulled off a plane Wednesday night while they tried to return to the U.S.
