Nebraska police are investigating reports of a shooting incident at a concert by rapper Tyga on Monday night.

The rap star had just completed a set at the Sokol Auditorium in Omaha when shots rang out following an altercation between Tyga's bandmates and audience members.

The angry encounter started when the frontman reprimanded fans who were throwing items onstage.

Tyga hissed, "Who threw this s**t? Who threw it? You threw it? See my outside... For real, you can meet me outside. I'm gonna do this one more motherf**king song for my fans and them I'm gonna go outside you b**ch-ass n**ga."

Police tell the shots were fired from a car as band members boarded their tour bus.

Two people on the bus suffered minor wounds.
