CHICAGO (AP) —  A former Chicago Police deputy superintendent who left to head police departments in Washington, D.C. and Philadelphia is returning to Chicago to help make changes to the police force.

Mayor Rahm Emanuel’s office issued a news release Sunday saying Charles Ramsey will be a senior adviser to the department and will help “guide civil rights reforms.”

The department has faced heavy criticism over its treatment of suspects since the November release of video showing a white officer shooting a black teenager 16 times. The video cost the police superintendent his job and prompted a federal civil rights investigation of the department.

Ramsey is a highly respected law enforcement figure and last year was named by President Barack Obama as the co-chair of the President’s Task Force on 21st Century policing.
