Australia's athletes have been banned from two of Rio de Janeiro's popular beaches after dark due to security concerns.
Australia's team chef de mission Kitty Chiller said athletes had been told not to go out onto the Copacabana and Ipanema beaches between 6 p.m. and 6 a.m. local time.

The decision was made in the wake of American six-time Olympic gold medalist Ryan Lochte having been held up at gunpoint on Sunday, while two Australian rowing coaches also were reportedly robbed at knifepoint shortly after the games' opening ceremony.
"We've put now the Copa and Ipanema beaches... the actual beach, the sand, off limits. There has been a lot of increased petty criminal — but criminal — activity on the actual beaches," Chiller told a news conference.
"We're also highly encouraging our athletes [to go elsewhere]. We've found a couple of areas in Barra to go to rather than traveling into town because the Copa-Ipanema downtown area seems to be where most of the unsavory activity is happening."

Australia had previously told athletes they had to travel in groups of three, while any travel after 6 p.m. local time must now be by vehicle — even for short distances.
"Obviously safety and security has always been the primary concern for all our athletes and all our team members," Chiller said. "We've introduced some further security and safety protocols for those people traveling especially to Copa and Ipanema area to ensure above all else we retain all our team members safely and securely."
