Riots break out in Baltimore, Maryland following the death of Freddie Gray in police custody.

On April 12, 2015, Baltimore Police Department officers arrested Freddie Gray, a 25-year-old African American resident of Baltimore, Maryland. Gray's neck and spine were injured while he was in a police vehicle and he went into a coma. On April 18, there were protests in front of the Western district police station. Gray died on April 19.

Further protests were organized after Gray's death became public knowledge, amid the police department's continuing inability to adequately or consistently explain the events following the arrest and the injuries. Spontaneous protests started after the funeral service, although several included violent elements. Civil unrest continued with at least twenty police officers injured, at least 250 people arrested, 285 to 350 businesses damaged, 150 vehicle fires, 60 structure fires, 27 drugstores looted, thousands of police and Maryland National Guard troops deployed, and with a state of emergency declared in the city limits of Baltimore. The state of emergency was lifted on May 6. The series of protests took place against a historical backdrop of racial and poverty issues in Baltimore.On May 1, 2015, Gray's death was ruled by the medical examiner to be a homicide. Six officers were charged with various offenses, including second-degree murder, in connection with Gray's death. Three officers were subsequently acquitted; in July 2016, following the acquittals, Baltimore City State's Attorney Marilyn Mosby dropped charges against the remaining three officers.
