Six-time Olympic gold medalist swimmer Michael Phelps has been charged with driving under the influence.
A Maryland State Police trooper in Salisbury stopped the athlete last Thursday at 11:30 p.m., authorities said Monday.
"Last week, I made a mistake," Phelps said Monday night, as quoted by The Washington Post. "Getting in a car with anything to drink is wrong, dangerous and unacceptable. I'm 19 but was taught no matter how old you are, you should always take responsibility for your actions, which I will do."
He added: "I'm extremely sorry for this. ... That's all I can say right now."
The trooper pulled Phelps over after he failed to halt at a stop sign, the Baltimore Sun reports. (Phelps, who made a splash at the Athens Summer Games, is a Baltimore County resident) He was arrested and later charged with driving under the influence of alcohol, driving while impaired by alcohol, violation of a license restriction and failure to obey a traffic-control device.
Two other passengers were in the car with Phelps when he was stopped in his 2005 Land Rover.
Police say the swimmer was cooperative during the entire process, though The Post reports that police spokesman Maj. Greg Shipley, citing the force's confidentiality code, declined to say whether Phelps submitted to a blood alcohol test.
