United States swimmers Ryan Lochte and James Feigen are wanted by police in Rio after reporting a robbery at gunpoint following their involvement in the Olympic Games.
The alleged incident took place on Sunday, after the duo - along with compatriots Gunnar Bentz and Jack Conger - had attended a party they were invited to by Brazilian swimmer Thiago Pereira.
Patrick Sandusky, chief external affairs officer for the United States Olympic Committee, confirmed police were seeking to speak further with Lochte and Feigen.
"Local police arrived at the Olympic Village this AM and asked to meet with Ryan Lochte and James Feigen and collect their passports in order to secure further testimony from the athletes," said Sandusky in a statement released on Wednesday.
"The swim team moved out of the village after their competition ended, so we were not able to make the athletes available.
"Additionally, as part of our standard security protocol, we do not make athlete travel plans public and therefore cannot confirm the athletes' current location.
"We will continue to cooperate with Brazilian authorities."
It has been reported that Lochte, who took his Olympic medal tally to 12 with a gold in the 4x200 metre freestyle relay last week, has already returned to America.
