Arizona police arrested Charles Barkley last night on charges of driving while impaired.

The AP reports an officer pulled Barkley over in Scottsdale after noticing that he ran a stop sign.

Charles Barkley was arrested on suspicion of drinking and driving early Wednesday morning.

An officer with a law enforcement task force that targets drunken driving saw the former NBA star run a stop sign around 1:30 a.m., said Gilbert police Lt. Eric Shuhandler.

Sir Charles declined a breath test but was given a blood test. Results are not yet available.

While we wait for more word, we can check out pictures taken at the mobile command post, where the blood tests were administered. People snapped pictures with their phones, which (natch) appeared on TMZ.
