Michael Phelps Arrested For DUI

Police pulled over Phelps, 29, at 1:40 a.m. for speeding, as he was traveling 84 mph in a 45 mph zone. Police also noted that Phelps, who was driving his white 2014 Land Rover, was crossing double lane lines on the road. Upon speaking with Phelps, the officer determined that he was likely intoxicated and asked him to submit to a field sobriety test.

"Mr. Phelps was identified as the driver by his driver’s license and appeared to be under the influence. He was unable to perform satisfactorily a series of standard field sobriety tests," a spokesperson for Maryland Transportation Authority told ABC.

Phelps was released from police custody on Tuesday after he was charged with the DUI, speeding and crossing double lane lines.

Phelps previously was arrested for a DUI in 2004 at age 19, not long after he’d collected eight medals at the Olympic Games in Athens, Greece. The athlete ultimately pleaded guilty to the charge and received 18 months of probation as punishment.

While Phelps, who has picked up 22 medals (18 gold) in his Olympic career, retired following London 2012, he announced that he was getting ready to compete again earlier this year and planned on appearing at Rio de Janeiro 2016.
