A watchdog group wants the state police to be the sole agency investigating the fatal shooting of an unarmed 35-year-old Detroit man by a Dearborn police officer.
Both the state police and Detroit police are investigating Kevin Matthews' death.
But the Detroit Coalition Against Police Brutality says it's concerned about the Detroit Police Department's role in the probe.
Matthews was shot multiple times Wednesday following a foot chase and struggle with the unnamed officer.
Police have said he was involved in an earlier larceny in Dearborn and was wanted by another police agency on a misdemeanor warrant.
Detroit Police Chief James Craig has said the officer suffered minor injuries and that his uniform was ripped during the struggle.
The coalition also has called for the officer's suspension.
