Minneapolis Police Chief Brian O'Hara has resigned following an internal investigation into his conduct, Mayor Jacob Frey announced Tuesday evening.

O'Hara began leading the Minneapolis Police Department in 2022, taking over during a period of significant upheaval for the department following the 2020 police killing of George Floyd. His appointment came as the city worked to rebuild public trust and implement reforms within the police force.

The mayor's office confirmed the resignation but did not immediately provide details about the nature of the internal investigation that led to O'Hara's departure. The investigation's findings and timeline have not been made public.

O'Hara's resignation marks another leadership change for the Minneapolis Police Department, which has faced ongoing scrutiny and calls for reform since Floyd's death sparked nationwide protests and demands for police accountability. The department has undergone significant changes in leadership and policies during this period of transformation.

The city will now need to begin the process of selecting a new police chief to lead the department as it continues its reform efforts and works to address community concerns about policing practices.
