American swimmer Ryan Lochte says armed robbers posing as policemen put a gun to his head and took his money in Rio de Janeiro. Lochte described the late-night encounter to NBC's "Today" show. The U.S. swimmer, who won gold in the 4x200 relay at the Rio Games, says armed men came out with a badge and pulled a taxi carrying him and three other American swimmers over. Lochte says they were told to get down on the ground, but he didn't and they put a gun to his forehead. He says the robbers took money and his wallet, but left his cell phone.
