A man was arrested for opening fire outside JJ Madison's All American Grill near Power Road and University Drive.
According to the police report, 30-year-old Chauncey Michael Cook was "kicked out of the bar" for being intoxicated and disruptive Sunday night.
After Cook left the bar, he walked outside and shot nine rounds in a sign at a nearby car wash. Police say this happened approximately 10 feet from the bar's entrance and the parking lot was full of parked cars and numerous people.
Several patrons ran back inside the building fearing for their safety and locked the door to prevent Cook from re-entering.
Police say a witness to the shooting called 911.
When officers arrived at the scene, they found Cook with the handgun inside his pants pocket, along with several blue prescription pills. The pills were identified as Alprazolam, a drug used to treat anxiety and panic disorders -- sold under the Xanax name.
Alprazolam is listed as a Schedule IV controlled substance by the Drug Enforcement Administration and a dangerous drug per Arizona Revised Statutes.
In the report, police say Cook knowingly carried the handgun into the bar concealed and stated that he observed several signs posted about firearms being prohibited.
A records check confirmed that Cook, a Mesa resident, is a convicted felon and prohibited possessor.
He faces numerous charges, including unlawful discharge of firearms, drug possession and criminal damage.
No injuries were reported.
