Mel Gibson has launched a court battle to wipe a drunk-driving charge from his police record.

The Braveheart actor was arrested in June 2006 after getting behind the wheel while intoxicated, and was sentenced to three years' probation the following month on a misdemeanor driving under the influence (DUI) charge.

Now the star has filed legal papers, obtained by TMZ.com, that indicate his lawyer will be in court in October to ask a judge to expunge the DUI from his record because he has completed the terms of his probation.

Gibson successfully attended a 12-step program for 11 months, underwent an alcohol abuse education course, and also handed over his driver's license for 90 days as part of his rehabilitation.
