Demonstrators have disrupted business at a large suburban St. Louis shopping mall to protest a grand jury’s decision not to indict the police officer who fatally shot Michael Brown in nearby Ferguson.

At least 200 protesters gathered on one of the busiest shopping days of the year Friday at the Galleria mall in Richmond Heights, about 10 miles south of Ferguson.

Several stores lowered their security doors or locked outside entrances as protests sprawled onto the floor while chanting, “Stop shopping and join the movement.”

It didn’t appear that any arrests were made.

Similar Black Friday protests were occurring at shopping areas in other parts of the country, including elsewhere in the St. Louis region.
