Police Search for Cab Driver After US Olympic Swimmers Robbed by Armed Men in Rio

"We apologize to those involved," said a Rio spokesman.

— -- Police are searching for the cab driver who was driving Ryan Lochte and other Team USA swimmers when they were robbed Sunday morning in Rio, a Rio Olympics spokesman said today.

Police have reached some of the athletes involved and are now looking for the cab driver, said Mario Andrada, a spokesman for Rio 2016. There are no additional updates in the investigation, Andrada added.

Four members of the U.S. Olympic Swimming Team -- Lochte, Gunnar Bentz, Jack Conger and Jimmy Feigen -- were robbed by armed men early Sunday morning while in a taxi headed for the Olympic Village, according to the United States Olympic Committee.

Their taxi was stopped by individuals posing as armed police officers who demanded money and other personal belongings.

"We got pulled over, in the taxi, and these guys came out with a badge, a police badge, no lights, no nothing just a police badge and they pulled us over," Lochte told NBC News.

"They pulled out their guns, they told the other swimmers to get down on the ground -- they got down on the ground. I refused, I was like we didn't do anything wrong, so -- I'm not getting down on the ground," he said.

"And then the guy pulled out his gun, he cocked it, put it to my forehead and he said, 'Get down,' and I put my hands up, I was like 'whatever.' He took our money, he took my wallet -- he left my cell phone, he left my credentials."

All four athletes were safe and cooperating with authorities, the Olympic Committee said.

"We apologize to those involved and once again we regret the fact that violence is a situation in these games," Andrada said at today's news conference.
