OAKLAND POLICE | Oakland Police Chief Howard resigned Wednesday morning citing medical reasons.

Jordan was named interim police chief in October 2011 within the thicket of the growing Occupy Oakland movement following the resignation of Anthony Batts, who was sharply critical of city administration’s torpid bureaucracy. Oakland Mayor Jean Quan officially named Jordan the permanent chief in February 2012.

His retirement ends 24 years at the department and comes at a time when long-avoided police reforms appear to be on the verge of implementation.

Federal Monitor Robert Warshaw has been highly critical of the pace of the department and administration’s adherence to reforms just as former Los Angeles and New York City Police Chief William Bratton was hired by the city as a consultant and the naming of former Baltimore Police Commissioner Thomas Frazier as compliance officer earlier this year.

Below is Jordan’s statement today:

This morning I advised City Administrator Deanna Santana that, effective immediately, I am on medical leave and taking steps toward medical retirement. This decision has been difficult, but necessary. Through my 24 years of wearing an OPD badge and uniform, I have emulated the Department’s core values: Honesty, Respect, and Integrity – values I observed in the men and women who worked with me and for me. I know that the members and civilian staff of the Department will carry on these values to generations to come. It has been an honor to serve the City of Oakland.

UPDATE: The East Bay Express reports Jordan’s unspecified medical condition is “serious,” according to Councilmember Libby Schaaf.
