Multiple sources told NBC Sports that Conger and Bentz cleared security and were in their seats on the plane when authorities came on to the aircraft shortly before takeoff and removed the swimmers.

They are being held at the airport but are being treated well and cordially, the sources told NBC. Authorities have indicated they don’t want to hold the swimmers long, but do want to know what happened during the early morning robbery, the sources said.

The root of the problem for the Brazilian authorities is seemingly contradictory versions of the robbery by Lochte and Feigen. NBC News reported Lochte told police there was one robber, while Feigen said there were more, one of whom had a gun.

The men also said the robbery took place on the way home from a club, which they left at 4 a.m. But security video showed them leaving at a different time, the judge said.

A Brazilian judge ordered Wednesday that the passports of American swimmers Ryan Lochte and Jimmy Feigen be seized, confining them to the country as authorities investigate their robbery claim.
