Detroit's police chief isn't yet certified as an officer in Michigan.
The Michigan Commission on Law Enforcement Standards said they haven't yet received paperwork from James Craig.
Craig started the job in July.
Detroit police spokeswoman Kelly Miner says in a statement that the MCOLES certification isn't required as police chief, but that Craig plans to complete the process voluntarily.
The issue came up after Craig told residents attending a program Monday on how not to get carjacked that he barely avoided one in recent weeks. He said he drove away after someone ran toward his vehicle.

Complete statement from Detroit Police Department:
"Chief James Craig is a veteran police officer with over 36 years of experience. Chief Craig is no stranger to constitutional policing and proper policing tactics. He previously worked here for The Detroit Police Department, as well as the Los Angeles Police Department. Chief Craig also headed the Portland, Maine and Cincinnati, Ohio Police Departments.
MCOLES certification is not required to serve as a police chief, yet Chief Craig voluntarily intends on completing the process to become a fully MCOLES certified law enforcement officer."
