Report: Inmate claims Freddie Gray intentionally injured himself

New information has emerged that raises more questions about the death of Freddie Gray, the man who died while in police custody in Baltimore last week.

According to a police document obtained by The Washington Post, an unnamed prisoner riding in the same transport van as Gray, who was separated from him by a metal partition, told officials he heard Gray "banging against the walls" of the vehicle and believes he "was intentionally trying to injure himself."

Twenty-five-year-old Gray died April 19 in police custody after suffering a spinal injury, though it's unclear exactly when or how it happened. Baltimore police and the U.S. Department of Justice are currently investigating his death.
