Demonstrators marched in downtown St. Louis for a third day of protests over a white former police officer's acquittal in the death of a black man.
Officers in full riot gear faced off against hundreds of people breaking shop windows and knocking over planters, resulting in dozens of arrests.
Another round of protests is expected today.
On Friday a judge acquitted former police officer Jason Stockley in the 2011 shooting death of Anthony Lamar Smith.
