The Justice Department has confirmed it will investigate the Baltimore Police Department for a potential pattern of unconstitutional policing in the wake of the death of Freddie Gray. The move comes one day after a request for such a probe from Baltimore Mayor Stephanie Rawlings-Blake. Six officers were indicted for Gray’s death on Friday. Federal investigators are already looking into whether Gray’s civil rights were violated. Attorney General Loretta Lynch said the federal government has a responsibility to look into potential abuses.

Attorney General Loretta Lynch: “When there are allegations of wrongdoing made against individual officers and police departments, the Department of Justice has a responsibility to examine the evidence and, if necessary, to help them implement change.”

Justice Department reviews of other police forces nationwide have led to consent decrees that mandate changes.
