That's So Raven Star Arrested For DUI Warrant

TMZ broke the story ... Brown was popped for DUI in August -- but struck a plea deal, dodging a jail sentence. As part of the deal, Brown had to complete an alcohol education program.

But law enforcement tells TMZ, Brown failed to show proof he had enrolled in the class -- so the judge issued a bench warrant. We're told Brown also failed to pay $1,908 in fines and court fees.
