Mel Gibson was interviewed by child welfare officials in Los Angeles on Wednesday.

The actor, 54, had a formal visit from the Los Angeles County Department of Children and Family Services at his home in Malibu this week following allegations by his ex-girlfriend Oksana Grigorieva accusing the Mad Max star of assaulting her and their eight-month-old daughter Lucia, RadarOnline.com reports.

“The meeting lasted for several hours.”

The couple are in the middle of a bitter custody battle that’s left Mel under investigation by Los Angeles Police detectives over the alleged Jan. 6 assault. Oksana, 40, claims he punched her in the head during a violent encounter while she was holding the baby, leaving the Russian crooner with broken teeth and the tot with a mark on her chin.
