Warmachine -- which is the fighter's legal name -- was arrested outside a bar called Thruster's Lounge around 11 pm.
Law enforcement sources tell us Machine and another male were fighting with bouncers -- and when cops tried to approach the situation, War Machine took off running.
Eventually, cops caught up with the 28-year-old -- threw him in handcuffs, and for some reason, put a spit bag over his head ... which is generally applied when the perp gets a little too aggressive with his oral fluids.
Machine was arrested for assault with a deadly weapon -- though it's unclear what the weapon is. He's currently being held in a SD jail.
This is after posting the following to his twitter account only two days ago (incidentally, a summary of his updates from the past few days about changing his ways was posted earlier this morning here):
I changed my Twitter name, make a note of it. Time for War Machine to get his life on track. No more trouble, no more porn. I’m going to train hard, win my fights, and get back in the UFC. By November my partners and I will be opening a new gym in Washington State. I’m going to get married in June, start living a good life. Too much BS in the last few years, I’m making a HUGE change, life’s too short to spend it being a f**k-up.
Wow, this guy is seriously what made me get in to twitter. It's sad perhaps, but there's nothing you can do about a guy that keeps geeting in to trouble except watch in disbelief.
Good news for warmachine though is that it doesn't appear the club he was busted outside this time was gay bar (although "Thruster's Lounge" does sound very suspicious).
