Jamar Clark was killed during a struggle with Officers Mark Ringgenberg and Dustin Schwarze, who are white, in November 2015. The incident came at a time of intense debate in the United States over police use of force in minority communities and Clark's death sparked protests where dozens where arrested.
"The officers will not be criminally charged and we have concluded there were no violations of MPD policy," police chief Janeé Harteau told a news conference on Friday.
