CHICAGO --Protesters briefly blocked the entrance to a Michigan Avenue Apple Store, chanting, "No justice, no profits." Police on bikes slipped behind the protesters to secure the store's entrance.

Most shoppers on the street Thursday seemed undeterred, some walking through groups of protesters.

Earlier today more than 50 protesters gathered on a bridge over the Chicago River before heading down Michigan Avenue.

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 shoot a black teenager 16 times. Protesters are critical of the police department's treatment of suspects, particularly black ones.

The protest is smaller than one held in the same shopping district on Black Friday. Many protesters are holding signs that read "Rahm Resign," which are aimed at Chicago's mayor, Rahm Emanuel.

Officer Jason Van Dyke has been charged with first-degree murder in the October 2014 killing of Laquan McDonald.
