Baltimore protests turn violent

Mayor demands answers to black man's unexplained injury while in police custody

Protesters rampaged through downtown Baltimore, Maryland, on Saturday, as the city's biggest demonstration thus far turned violent over the death of a young black man in police custody.

Holding signs reading "Black lives matter!" and "Justice for Freddie Gray!", at least 2,000 protesters marched toward City Hall, where they demanded justice for Gray, 25, in a peaceful 90-minute rally. Gray died on April 19 from spinal injuries a week after his arrest.
