EXCLUSIVE AUDIO: The Tape That Could Destroy Mel: "No One Will Believe You", He Says After She Charges: "You Hit The Baby"

And Mel, raging at Oksana, is caught on audio telling her: “I want my child, and no one will believe you.”

It may be the most damaging tape against Mel yet. RadarOnline.com has released five other audio portions with Mel spewing vile, racist rants, threatening Oksana and telling her she “f*cking deserved it” after she complained that he hit her.

But this, the sixth excerpt released exclusively by RadarOnline.com, may have the most serious consequences for Gibson, as a criminal investigation has been launched against him while he and Oksana battle in court for custody of their eight-month-old daughter Lucia. An investigation by the Department of Children and Family Services is also ongoing.

In the crucial part of the newly released tape, Oksana refers to January 6, the night she alleges Mel punched her in the face and damaged her two upper front teeth.

RadarOnline.com was first to report that Oksana told law enforcement authorities she was holding Lucia, who was two months old, when Mel punched her. And RadarOnline.com broke the news on Thursday that Oksana says she has a photograph of the baby with a bruise on her face after the incident.

In this new tape, Oksana refers to that incident and tells Mel that there is something wrong with him and he needs medication. This is the recorded dialogue after she says that:

Oksana: You cannot raise the child with these symptoms.

Mel: What?

Oksana: You’re acting as a crazy man right now and you have been for many, many months. And you hit me, and you hit her (Lucia) while she was in my hands! Mel, you’re losing your mind. You need medication.”

Mel: You need a f*cking kick up the a** for being a b*tch, c*nt, gold digging whore! With a p*ssy son! And I want my child, and no one will believe you! So f*ck you!”

While there is cross talk as Oksana and Mel argue, Oksana’s team views it as an admission that Mel hit the baby when he punched Oksana and damaged her front teeth, the source close to the situation told RadarOnline.com exclusively.

WARNING: This audio contains graphic and profane language. It has been left unedited so that the full impact of Mel’s rant can be heard. RadarOnline.com has not altered this tape in any way.

And RadarOnline.com also has exclusively reported that DCFS wants to talk to Mel this week. They interviewed Oksana’s 12-year-old son Alexander on Friday. Two detectives from the special victims unit were at the courthouse on Thursday waiting to testify in the closed hearing on the Mel-Oksana case.

This new tape, obtained exclusively by RadarOnline.com, features more profane tirades by the Braveheart actor against his girlfriend of three years.

As he loses control he yells at her:  “I’m not giving you my house and you can rot unless you crawl back, s*ck my cock and say you’re sorry, in that order! Do you understand me? You f*cking offend my f*cking maleness, my masculinity, my being, my soul!”

In a tape previously released by RadarOnline.com, Gibson threatened to burn down the house after demanding sex from Oksana.

On the new tape, Mel and Oksana argue over custody of Lucia and Oksana tells him: “I’m just saving my child’s life because you are a monster! That’s all! You’re a monster!”

But Mel threatens that he will gain custody of their baby and tells Oksana:

“You have my child and she doesn’t need a gold digging, f*cking Russian c*nt, wh*re for a mother! We all know what you are! I will have that child, easily.

Oksana replies, “I’m sorry? You will not have this child.”

Mel answers: “They won’t let you keep her because they’ll know what you are!”

He also keeps up his attack that she has used him for money and Oksana points out that she has signed a document giving up her claim to his fortune.

And, echoing the sick racist rant where he told Oksana she would be raped by a “pack of n***ers” for dressing too provocatively, Gibson again tells her she will be raped.

He says: “If you get raped it’s your fault, for starters. Showing off your fake t*ts! Like they’re some special deal? How much did they cost, those fakers?”

Oksana continually tells Mel that there is something wrong with him mentally , and at one point he answers,  “You need to say a lot to assuage my insanity because you’ve made me this way!”

She fights back and tells the star, “And you yell and scream and threaten everybody around you. Everybody’s pussy-footing around you because they’re all scared sh*tless out of you.”

The tapes were recorded by Oksana this year. She told sources that she taped Mel because he threatened her life and he is heard issuing several threats on the tapes released exclusively by RadarOnline.com.

At one point he threatens to hit her in the side of the head with a shovel and another time he tells her he will bury her in the rose garden.

RadarOnline.com’s explosive tapes have dominated headlines and are causing public figures to ask if Mel Gibson’s career is over.

Mel’s lawyers have not commented to us on the tapes. They have not disputed it is Mel’s voice spewing the racist invective and threats on the tapes.

The tapes are also in the hands of law enforcement and under seal in court. They may or may not be used as evidence against Mel in any criminal case, but as RadarOnline.com was first to report they supplement other evidence that Oksana has against Mel.

The Russsian-borne musician has photographs of her broken front teeth after she claims Mel punched her and her son was a witness to the events of January 6. Oksana has told law enforcement that after Mel broke her front teeth that night, got a gun and waved it in her face, threatening her life.

RadarOnine.com released an exclusive photo of Oksana’s damaged teeth last Friday
