MINNEAPOLIS (AP) — State agents are investigating Wednesday after a Minneapolis police officer was involved in a shooting downtown.

Bureau of Criminal Apprehension spokeswoman Jill Oliveira confirmed her agency was investigating. She gave no other details. Minneapolis police didn’t immediately respond to messages.

Nekima Levy Armstrong, a longtime activist on policing and civil rights issues, posted that she received a call from interim Chief Amelia Hoffman to tell her that police had shot and killed a man while serving a warrant Wednesday morning.

Armstrong was among several people whom Mayor Jacob Frey last year named to a commission aimed at improving public safety in the city.
