Reality TV star Dog the Bounty Hunter has announced he intends to go after the alleged attacker of porn star Christy Mack.
Mack was seriously injured in an assault – which she claims was at the hands of her former boyfriend mixed martial arts fighter Jon Koppenhaver - at her Las Vegas home on Friday.
Koppenhaver, whose ring name is War Machine, had been given until 7pm on Tuesday to surrender to police.

The famous bounty hunter became involved in the matter after he was contacted directly via a member of Mack’s family, TMZ reports.
Porn star Christy Mack sustained serious injuries in the attack
It adds War Machine is facing seven criminal charges following the incident last week.
On Monday Mack tweeted pictures of her injuries and gave an account of what occurred.
She claimed Koppenhaver arrived at her house on Friday, where he found her with one other “fully clothed and unarmed” person in her Las Vegas home.

She wrote: “Without a single word spoken, he began beating my friend; once he was finished, he sent my friend away and turned his attention to me. He made me undress and shower in front of him, then dragged me out and beat my face.
“I have no recollection of how many times I was hit, I just know that my injuries resulted from my beating.
“My injuries include 18 broken bones around my eyes, my nose is broken in 2 places, I am missing teeth and several are broken. I am unable to chew, or see out of my left eye.
Among her injuries were 18 broken bones around her eyes and a ruptured liver
“My speech is slurred from my swelling and lack of teeth. I have a fractured rib and severely ruptured liver from a kick to my side. My leg is so badly injured I have not been able to walk on my own.”
Mack, who says Koppenhaver broke up with her in May, added: “I also attained several lesions from a knife he got from my kitchen. He pushed the knife in me in some areas such as my hand, ear, and head. He also sawed off much of my hair with this dull knife.
Mack tweeted images of her injuries from her hospital bed on Monday
“After some time, the knife broke off the handle and [he] continued to threaten me with the blade.
“I believed I was going to die. He has beaten me many time before, but never this badly.”
Mack also claims Koppenhaver attempted to rape her but was unable to carry out the act.
She was able to run out the house, naked and bloody, to neighbours who took her to hospital.

Koppenhaver remains at large and Mack says there is a $10,000 reward being offered for his capture.
Meanwhile the fighter has apparently been tweeting from his verified account since the incident.

He wrote: “I can’t believe this…I must be cursed… I’m not a bad guy, I went to surprise my gf, help her set up her show and to give her an engagement ring and ended up fighting for my life.”
On Monday he wrote: “The cops will never give me fair play, never believe me. Still deciding what to do but at the end of the day it’s all just heart breaking.”
He has not responded to Dog's tweets.

The Las Vegas Review Journal writes Koppenhaver was arrested on a felony charge of domestic violence with strangulation, which was dismissed, and a misdemeanour charge of domestic violence with battery in 2009.
Koppenhaver pleaded guilty to the misdemeanour charge and was ordered to complete a course of counselling, it reports.
