Detroit Mayor Dave Bing has appointed two new assistant chiefs as part of a restructuring of the city's police department.
Janice Butler was lured out of retirement and named Thursday to become assistant chief for administration, while deputy chief Paul Welles has been moved up to assistant chief for patrol and investigation.
Police commissioners still have to approve the appointments.
Commander James White also has been moved up to deputy chief, while two deputy chiefs under ex-chief Ralph Godbee have been reassigned.
Godbee resigned last month after a female subordinate revealed the two had been in a sexual relationship.
Bing says 26 officers will be promoted to sergeant, lieutenant and inspector ranks.
The mayor says the changes are designed to improve police operations and reduce crime.
