Retired Olympian Michael Phelps has pleaded guilty to driving under the influence.

The decorated swimmer was pulled over for speeding in Baltimore, Maryland in October (14) and booked after failing a field sobriety test.

He was subsequently charged with driving under the influence, excessive speeding and crossing double lanes, and was hit with a six-month suspension from USA Swimming-sanctioned competitions.

Following the arrest, Phelps announced he was seeking professional in a bid to deal with his issues, and, on Friday (19Dec14), the swimmer took another step to put the incident behind him and pleaded guilty to the charges.

He was given a one-year suspended sentence and 18 months probation, according to Tmz.com.

This is the second Dui plea for Phelps - in 2004, he was sentenced to 18 months probation after he pleaded guilty to driving while impaired in Maryland.
