Phoenix, Arizona area officials are investigating a reported incident involving Lil Wayne’s tour bus and three other buses associated with the ongoing ‘America’s Most Wanted Music Festival’.

According to reports uncovered by TMZ, stones and bottles were thrown at Lil Wayne’s tour bus after a concert and police say at least one shot was fired.

Police say it all went down when 2 buses from his 4-bus entourage stopped at a nearby apartment complex. When a group of women were spotted getting on and off the buses people in the complex began to get violent and began throwing stones and bottles.

While it’s unclear who fired the alleged gun shot, one complaint has surfaced from a fifteen year old boy who alleges that the rapper’s bodyguards roughed him up, bruising some of his ribs.
