4名美国游泳运动员在枪口下被抢劫。

Rio de Janeiro, Brazil (CNN)Olympic medalist Ryan Lochte and three other U.S. swimmers were safe and cooperating with police Sunday after being robbed at gunpoint in Rio de Janeiro, the U.S. Olympic Committee said. One of the bandits reportedly put a gun to Lochte's forehead. 

Lochte and fellow swimmers Gunnar Bentz, Jack Conger and Jimmy Feigen had left a hospitality house hosted by France early Sunday morning in a taxi bound for the Olympic Village.
