Brazilian police have pulled two US Olympic swimmers off a plane at Rio airport for questioning. <br /><br /> They were part of a group of four swimmers, including gold medalist Ryan Lochte, who claimed they were robbed at gunpoint in a taxi in the city on Sunday. <br /><br /> Team USA members Jack Conger and Gunnar Bentz were stopped as they tried to board a flight home after doubts were raised about their account. <br /><br /> Authorities have queried video footage which apparently showed the swimmers in good spirits after the alleged mugging. Olympic Village X-ray machine records also suggest the men were carrying belongings they claimed had been stolen.<br /><br /> Lochte has already returned to the US, while the pair’s other teammate James Feigen, is reported to be communicating with Brazilian authorities. His exact whereabouts, however, still remain unclear.<br />
