Bobby Brown Arrested

Law enforcement sources tell us, Brown was pulled over around 1AM when police observed the singer driving erratically on an L.A. street.

According to law enforcement sources, officers approached Brown's vehicle and detected a strong odor of alcohol -- at which point they asked Brown to get out of his car.

We're told Brown performed a field sobriety test, but didn't do very well -- so he was arrested on suspicion of DUI.
