Baltimore Police said 15 officers were injured by protesters throwing bricks, rocks and other items at police hours after a funeral for Freddie Gray, who died of a mysterious spinal injury while in police custody.
Two remained hospitalized Monday evening.
Maryland Gov. Larry Hogan declared a state of emergency in the city and activated the state’s National Guard early in the evening.
In a statement the Republican governor said that violent demonstrations “will not be tolerated” and crimes related to them will be prosecuted.
Protestors jumped on a police car and destroyed it, and set another vehicle ablaze. They also looted and later burned a CVS Pharmacy after having attacked other businesses, including a check-cashing service.
On live CNN footage, someone at the burning CVS took a knife and cut into the hose that firefighters had hooked up to a hydrant in an effort to put out the blaze.
