MINNEAPOLIS (AP) - Police have arrested demonstrators who were blocking rush hour traffic on an interstate in downtown Minneapolis.

About three dozen protesters blocked southbound Interstate 35W near University Avenue Wednesday morning before state troopers moved in, arrested them and put them on a bus.

They are protesting police brutality, including the fatal shooting of Philando Castile by a suburban St. Paul officer during a traffic stop last week.

Some demonstrators walked onto a bridge across the Mississippi River and chanted "I believe that we will win."
