The justice department began investigating the police force for the Tennessee city in 2023, after the death of Tyre Nichols, who was brutally beaten by police during a traffic stop.

In its report from the investigation, released on Wednesday, the department said Memphis police “must correct these issues” that it said were part of a “pattern” of civil rights violations.

In response to the justice department’s report and calls for change, the mayor of Memphis, Paul Young, said on Thursday that the city has already enacted reforms.

While the report acknowledged these changes, it also said there are “additional remedial measures” needed “to fully address” the listed issues.
