Michael Phelps has been arrested for allegedly driving under the influence early Tuesday morning.
The American swimmer, 29, who is also the most decorated Olympian in history with 22 medals to his name, was also charged with crossing double land lines and excessive speeding.
He was pulled over by the Maryland Transportation Authority Police after he travelled through the Fort McHenry Tunnel on I-95 in Baltimore.
Police claim he was speeding at 84 mph in a 45-mph zone. He was later released.
A spokesman from USA Swimming said: "The news regarding Michael Phelps and his actions are disappointing and unquestionably serious. We expect our athletes to conduct themselves responsibly in and out of the pool."
It is the second arrest for the athlete. He was first pulled over on a DUI offence in 2004 when he was just 19 and later sentenced to 18 months’ probation.
“I recognize the seriousness of this mistake,” he said in a statement at the time.
“I've learned from this mistake and will continue learning from this mistake for the rest of my life.”
Other controversial Phelps moments include the time he was photographed with a marijuana pipe at a party in 2009. He was suspended from competition for three months by USA Swimming after the image surfaced in the press.
Phelps took a break from the sport briefly after winning four golds in London, but came out of retirement for the 2012 London.Reuse content
