British sailors Hannah Mills and Saskia Clark have been robbed at knife-point after a training session here.

The 2012 London Olympic silver medallists were chased by two men while walking back to their hotel on Flamengo beach, police said Thursday, reports Xinhua.

“Our delightful walk back from the sailing club to the hotel turned fairly nasty when two guys wielding seven-inch knives ran at us, pushed us around and grabbed everything we had,” Mills said on her Facebook page.

“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 pair, also 2012 world champions in the 470 class, are on a two-week training camp ahead of the Rio 2016 Olympics.

Police said they were investigating the incident and appealed for witnesses to come forward.
