DMX is back behind bars (again) after being arrested last night in Phoenix for violating the terms of his probation. According to reports, the troubled rapper, who’s on parole for an assault conviction, failed to check-in with his probation officer, and was summoned to court Thursday night. X is currently in custody and there’s no word on when he’ll be released.

This marks the sixth time X has been locked up in Maricopa County. The rapper was working on getting back on track and performed in Scottsdale, Ariz. last weekend. The performance made news after X went on an anti-Jay-Z rant during the show.

“New York to AZ, n—-s must be crazy. I’m the dog, f— Jay-Z!” X barked. “What do y’all think is the state of the rapper you see right now? I mean, you know, I’m an artist, so I kind of have biased views. But I think most of you n—-s suck. I think they not only suck, but they suck dick. Correct me if I’m wrong, but we’re real people.”

DMX has a probation revocation hearing set for November 24. Let’s hope the Dark Man can stay out of troubles for the remainder of 2010.
