Charles Barkley was arrested on suspicion of DUI early this morning in Arizona, reports TMZ. Sir Charles was stopped by the Gilbert Police Department with whom he appeared to be cooperative in these photos, shaking hands with officers. The Sixers legend was released and left the DUI checkpoint where he had been detained in a taxi. Barkley did not immediately return a text message we sent him this morning. If he gets back to us with a comment, we'll update here.
