Mel Gibson has sought treatment for alcoholism, his rep, Alan Nierob, tells PEOPLE.
"He definitely entered a program," said Nierob, who wouldn't identify or describe the program or say how long Gibson planned to be there.
Gibson was arrested on suspicion of driving under the influence in Malibu early Friday morning.
On Saturday, he issued a statement apologizing for his behavior after the arrest.
The Los Angeles Sheriff's Department turned its case over to the district attorney Monday. The DA's office is now reviewing the information to determine whether to press charges.
Controversy erupted this weekend over allegations that the Sheriff's Department sanitized an arrest report containing anti-Semitic and sexist remarks that Gibson allegedly made while in custody.
DA spokesperson Jane Robison tells PEOPLE, "We believe we received a complete report, but can't comment on the details of it." An arraignment is set for Sept. 28.
Meanwhile, a spokesperson for Disney said Monday that the studio plans to release Gibson's latest film, "Apocalypto," as scheduled on Dec. 8.
