Dog the Bounty Hunter vows to hunt down MMA fighter War Machine

This may be the most PR Dog the Bounty Hunter has gotten since his A&E show was canceled.

Hurling himself in the middle of a celebrity domestic-abuse case, the reality TV star who goes by Dog -- real name: Duane Chapman -- has vowed to find War Machine, the Spike TV/Bellator mixed-martial-arts fighter who is accused of savagely beating his girlfriend, porn star Christy Mack.

War Machine (who was born Jonathan Koppenhaver) last week took to Twitter and implied he was acting in self-defense, but according to reports he is still being sought by the Las Vegas police.

“You got 24 hours to turn your self in or I am coming after YOU!,” Chapman tweeted on Monday. He followed up with numerous tweets and retweets about the case.

The case has lifted a curtain on the amped-up underworld of MMF fighting, many matches of which are telecast on Viacom-owned Spike. Viacom acquired a majority stake in fight promoter Bellator in 2011. War Machine was under contract to Bellator but the company quickly dumped him after the beating allegation surfaced last week.

Chapman, meanwhile, is a real-life bounty hunter turned reality star. Back in 2003, he made headlines by capturing Andrew Luster, a Max Factor cosmetics heir later convicted of multiple rapes. Dog supporters have been using the hashtag #andrewluster to encourage him in his War Machine pursuit.

His show “Dog the Bounty Hunter” made Chapman a household name before it was canceled by A&E in 2012. Currently he stars in “Dog and Beth: On the Hunt” on CMT.
