CHICAGO (AP) - Police officers manning a bicycle barricade on Chicago's Michigan Avenue took two protesters into custody after a scuffle during which police bikes were overturned and officers and protesters grabbed and pushed one another.
There were no apparent injuries. The skirmish came about three hours into what had been a mostly peaceful demonstration.
The protest Thursday is the latest in a series of demonstrations in the city since the release last month of police video showing a white officer shooting a black teenager 16 times. A federal civil rights investigation of the city's police department is underway.
