San Francisco police officers use force against African Americans more often than against other racial groups, according to a 432-page federal report made public Wednesday.

The report, issued by the U.S. Department of Justice in response to charges of racial bias by San Francisco police, shows that 37% of the cases in which police used force between May 2013 and May 2016 involved African Americans, a larger percentage than any other ethnic group. Nine of the 11 people who were killed during use-of-force incidents in that time frame were also people of color.

In all, federal officials made 272 recommendations for reform in the report, which was requested by Mayor Ed Lee after Mario Woods, an African American, was shot at least 21 times by police in 2015.

“This report makes clear the significant challenges that lie ahead for the police department and the city,” Ronald Davis, director of the Department of Justice’s Community Oriented Policing Services Department, said in a statement. “More than 90 findings outlined in the report reflect key operational deficiencies in the police department.”
