Australian paralympian Liesl Tesch who has competed in six Paralympic Games has been robbed at gunpoint in the Brazilian city of Rio de Janeiro, BBC reports.
Tesch said a man brandishing a gun pushed her off her bicycle and stole it on Sunday. Australian Paralympic team physiotherapist Sarah Ross also lost her bicycle in the attack.
The Australian Olympic Committee has said Rio must improve security in the city in the aftermath of the robbery.
Chef de Mission Kitty Chiller said: "We're demanding that the level of security forces, which number about 100,000, is reviewed and also we are also asking that they are deployed earlier prior to Games time, especially around training and competition venues.
"It's not an isolated incident. It's got to a point now that steps and measures are taken to ensure that all our team members who go to Rio for the Olympic Games next month are safe."
