Olympic swimmer Michael Phelps said he is "deeply sorry" after he was arrested and charged with driving under the influence.
The 29-year-old was stopped at the Fort McHenry Tunnel in Baltimore in the US, and Maryland Transportation Authority Police said he was going at 84mph in a 45mph zone.
Phelps, the most decorated Olympian of all time with 22 Olympic medals, has made an apology on Twitter and said he takes "full responsibility" for his actions.

(3/3) I know these words may not mean much right now but I am deeply sorry to everyone I have let down.— Michael Phelps (@MichaelPhelps) September 30, 2014
Phelps was released after his arrest.
This is his second DUI charge in Maryland. A native of Baltimore County, the Olympic swimmer faced a similar charge in 2004 in the Eastern Shore area.
