 Police say responding officers found what they called an unruly crowd at the scene. One man was arrested for obstruction and unrelated warrants. Officers also recovered a gun at the scene. Longtime Minneapolis civil rights champion Spike Moss was honored today as the city renamed a section of Plymouth Avenue North after him. For more than 60 years, Moss has spoken out against racism, police brutality, and against community violence that has harmed or killed scores of African Americans over the years.
