A man was shot and killed early Saturday morning in downtown Minneapolis after a dispute erupted into gunfire, police say.

Minneapolis police responded to the shooting near 6th Street N. and Hennepin Avenue about 3 a.m. and found the victim, who had been shot and was not breathing, spokesman John Elder said. The man was "believed to be in his 20s."

Officers started CPR and tended to the wound until paramedics arrived and took the man to HCMC, where he died.

According to a preliminary investigation, the victim was shot during a dispute with another man. Police identified the 30-year-old suspect at the scene, arrested him and recovered a firearm.

The man was being held in the Hennepin County jail for probable cause murder, Elder said. The Star Tribune generally does not identify suspects until they are charged.

The Hennepin County medical examiner will identify the victim in the coming days.

The shooting is Minneapolis' 50th homicide of the year.

About 10 minutes after the downtown incident, police responded to a shooting at St. Mary's Avenue and Delaware Street SE, where they found another man suffering from a gunshot wound. The victim, who was "believed to be in his late teens," was hospitalized in critical condition.

Police had not arrested a suspect and were still investigating the shooting.

A third shooting occurred about 2:22 a.m. Saturday at the CC Club bar at 2600 Lyndale Av. S., where an angry patron exchanged gunfire with a bar employee, police said.

The suspect fled before officers arrived, later going to a Shakopee hospital with a noncritical gunshot wound, police said. The suspect was taken to HCMC.
