Robberies prompt calls for better Rio security

Australia's Olympic team leader is urging Brazilian authorities to implement Olympic-scale security in Rio de Janeiro "before an athlete gets hurt".

Two members of the Australian Paralympic sailing squad were robbed at gunpoint in Rio during the weekend, highlighting fears of crime against foreign athletes ahead of the Summer Games in August.

An estimated 85,000 police and soldiers will be patrolling the streets during the Olympics and Paralympics, but violent crime remains a fact of life in Rio.
