MINNEAPOLIS — Four people are injured after a shooting involving a party bus in downtown Minneapolis.

Police say officers were called to a shooting at about 2:30 a.m. Saturday near 3rd Street North and Hennepin Avenue.

Near 3rd Street and Nicollet Avenue, they found three adults who had gunshot wounds that were not life-threatening.

Police spokesman John Elder said all victims were “related or associated” with a party bus. They were taken to Hennepin County Medical Center by ambulance.

About an hour later, a fourth victim from the same incident arrived at the hospital.

The victims have not been identified.

Elders says the shooting suspect left the scene and there have been no arrests.
