Mel Gibson has met with detectives to discuss extortion claims against his ex-gf.

The  actor – accused of domestic violence against Oksana Grigorieva, the mamma of his nine-month-old daughter Lucia – met with detectives on Sunday (25.07.10) to discuss claims the Russian singer is trying to make money out of their split.

The actor now claims Grigorieva only released explosive audio tapes – documenting their vicious arguments and the alleged attacks made by the Hollywoodland star – after he refused her apparent demands for wonga.

Los Angeles County Sheriff’s Department spokesman Steve Whitmore confirmed that detectives had met with Gibson to discuss his allegations.

Whitmore explained: “It was not for the domestic violence investigation, it was just for the extortion.”

Gibson does not have to discuss his ex-partner’s claims based on his Fifth Amendment rights against self-incrimination – and during the meeting, the actor and his lawyer submitted “physical evidence” — including emails and texts – to make the case against Grigorieva.

Meanwhile, another photograph of the singer with a black eye after an alleged fight with Gibson has surfaced on the internet.

The close-up shot, revealed on RadarOnline which shows the 40-year-old beauty with deep bruises around her left eye, was reportedly taken in January after a heated argument with the ‘Braveheart’ star.

Gibson is now facing a criminal investigation on domestic battery charges by the Los Angeles County Sheriff’s Department and is part of a Department of Children and Family Services investigation.
