A massive march in Baltimore Saturday to protest the death of Freddie Gray, the 25-year-old black man who died of a spinal injury one week after being taken into police custody, stopped temporarily at Baltimore City Hall, where demonstrators pulled down and attempted to burn an American flag before replacing it with a black-and-white version.

The protest then moved on to Camden Yards, site of a Saturday night Orioles-Red Sox game, when car windows were smashed and objects thrown at police.
