Mel Gibson Arrested for DUI FRIDAY JULY 28, 2006 05:00PM EST Mel Gibson Photo by: Jeff Vespa / Wireimage Mel Gibson was arrested for a driving under the influence early Friday morning in Malibu, according to the booking report. Gibson, 50, was pulled over on the Pacific Coast Highway, sheriff's spokesperson Steve Whitmore tells CNN. Officers on patrol said Gibson was driving at an "excessively fast speed," according to Whitmore. "The investigation is ongoing," Whitmore told the Associated Press. "As we would do with anyone, we don't want to release any more since the information is fragmentary." Gibson was stopped at 2:36 a.m., charged with a misdemeanor and posted $5,000 bond, according to booking papers. Gibson's rep, Alan Nierob, said he was looking into the matter. Gibson, who has admitted to past problems with alcohol, ran a red light and collided with another car in 1984 while driving drunk. In 1991, he joined Alcoholics Anonymous. Gibson's 1995 film, Braveheart, which he directed and starred in, won Oscars for Best Picture and Best Director. His newest film, Apocalypto, set in the Mayan civilization of several centuries ago, is due out in December.
