The rear window of a Kalamazoo police car was broken during an otherwise peaceful protest tied to the shooting of an 18-year-old in Ferguson, Missouri.

The Kalamazoo Department of Public Safety says it has no suspects. The car was damaged Tuesday night as a crowd passed it. The protest drew 150 people a day after a grand jury in Missouri declined to file charges in the death of Michael Brown.

There were similar demonstrations in Detroit and on college campuses in Michigan.
