Olympic sailors Hannah Mills and Saskia Clark have revealed that they were robbed at knifepoint while training in Brazil.

The pair, who won silver medals at the London 2012 Games, were approached in Rio de Janeiro by two men carrying seven-inch knives as they walked back to the club hotel.

According to the Daily Star, the pair wrote on their Facebook page: "Back in Rio for 2 weeks training. Top News Today: We've been mugged.

"Our delightful walk back from the sailing club to the hotel turned fairly nasty when two guys wielding 7inch knives ran at us, pushed us around and grabbed everything we had.

"Along with the things that were actually worth something, the most annoying thing right now is our lycra we were sailing in got taken. Unbelievable!!"

The duo qualified in the 470 class for the Rio 2016 Olympics after earning bronze at the World Championships in Santander, Spain earlier this year.
