Mel Gibson to expose ex-girlfriend`s extortion plans

London: Hollywood actor Mel Gibson is planning to reveal all about his ex-girlfriend`s plans to extort money after she alleged he beat her and threatened her with a gun. Gibson is currently at the centre of a police investigation in Los Angeles after Oksana Grigorieva - the mother of his daughter Lucia - reportedly obtained a restraining order against him amid claims he punched her and knocked out a tooth during a heated altercation in January.

However, according to sources, Gibson denies the allegations and is now planning his own defence, reports a news website. He will present evidence to the authorities which will prove that Grigorieva tried to extort money from him, and threatened to leak their heated phone recordings to the press if he didn`t pay up. IANS
