Protests broke out in Chicago after a video was released showing police reportedly shooting a teenager 16 times.
ABC reports that the protesters were seen blocking a police building and chanting "16 shots" for the number of times the officer allegedly shot the teen
Some of the agitators were injured during the protest, according to the Chicago police.
The dash cam video, released a day ahead of a court-ordered deadline, shows officers confronting 17-year-old Laquan McDonald, who later died at a hospital, as he walked down the street on Oct. 20, 2014.
However, the Chicago police maintain that they were responding to a report of a person walking down the street with a knife and that McDonald refused to drop the knife when ordered.
