The United States Olympic Committee has apologized for what it called the unacceptable behaviour of four US swimmers in a bizarre incident at a petrol station in Rio.
The swimmers had claimed the group was robbed at gunpoint after their taxi was stopped.
CCTV footage however appears to prove the story was false, invented by the swimmers after they vandalised the petrol station and clashed with staff.
Lochte returned to the US on Monday. The other two, Gunnar Bentz and Jack Conger, were pulled off a flight in Rio on Thursday night but were later allowed to leave for the US, while Feigen remains in Brazil.
