The battery charge was another blow to Gibson’s reputation, which took a major hit after his 2006 arrest for drunken driving. A deputy’s report leaked to the celebrity website TMZ revealed the action star had used anti-Semitic and sexist slurs.

His conviction was later expunged.

Recordings leaked last year during his custody battle with Grigorieva also contained racist and sexist taunts by the actor during a series of tirades.

Gibson has not publicly addressed the recordings, which were given to sheriff’s investigators and widely circulated by the celebrity website RadarOnline.

The charges came a week before Gibson’s latest film, “The Beaver,” is due to premiere at the South by Southwest festival in Austin, Texas. It is only the second major film that Gibson has starred in since 2002.

He portrays a deeply troubled man able to communicate only through a beaver puppet in the film directed by Jodie Foster.

Although Gibson’s prominence as an actor has diminished, he has remained a Hollywood fixture and drawn audiences as a director.

His 2004 film “The Passion of the Christ” was a surprise blockbuster, earning more than $300 million.

His relationship with Grigorieva helped return Gibson to the limelight, with the pair appearing on red carpets and award shows. Gibson confirmed her pregnancy on “The Tonight Show.”

Grigorieva, 40, has a teenage son with actor Timothy Dalton.

Gibson is suspected of striking her on Jan. 6, 2010, although she did not report it until months later.

The Sheriff’s Department opened its investigation in July, and later began an ongoing probe into Gibson’s claim that Grigorieva had attempted to extort him.

By then, the pair had broken up and reached a confidential custody agreement regarding their infant daughter. Although the exact details are not public, Gibson’s attorney said last year the actor was paying for a house and car for Grigorieva along with child care.

The former couple has appeared opposite each other several times in a family law court that has heard issues related to child care, financial issues and evidence in the criminal investigations of both parents.

The district attorney’s office did not announce a decision Friday on whether Grigorieva would face any criminal charges.
