In a sixth tape posed Tuesday on RadarOnline.com, Mel Gibson loses it as his ex Oksana Grigorieva accuses him of hitting her and their infant daughter.

"You hit me, and you hit her while she was in my hands!" she tells him. "Mel, you’re losing your mind. You need medication."

Though he doesn't admit to abusing either one of them, Gibson, 54, can barely keep this cool.

“I want my child, and no one will believe you," he screams at her in the expletive-ridden conversation.

Gibson and Grigorieva, 40, are currently engaged in an increasingly ugly custody dispute over their daughter, Lucia.

On Friday, Radar posted shots of Grigorieva with two damaged upper front teeth, allegedly after a January fight with Gibson.

Sources tell UsMagazine.com that Grigorieva's claims are a ploy for more custody — and cash

Nevertheless, detectives at the Los Angeles County Sheriff's Department are currently investigating the incident. Detectives hope to speak to Gibson, who has yet to be interviewed.

Still no word if the case will be turned over to prosecutors, who will decide whether Gibson should face criminal charges.
