Brooklyn Center Police Chief Tim Gannon and Kim Potter, the officer who fatally shot Daunte Wright on Sunday, have both resigned.
Potter's resignation was confirmed shortly before a press conference held by Mayor Mike Elliott Tuesday, with Elliott then confirming Gannon had also resigned.
Brooklyn Center City Council had voted on Monday evening to recommend that both Gannon and Potter be fired.
A senior member of the department has been promoted to acting police chief.
In a letter issued via her union, which did not mention Wright, the 26-year veteran Potter said: "I have loved every minute of being a police officer and serving this community to the best of my ability, but I believe it is in the best interest of the community, the department, and my fellow officers if I resign immediately."
Potter was identified Monday evening as the officer who shot the 20-year-old Wright during a traffic stop Sunday afternoon, sparking large protests and civil unrest in the north metro city on Sunday and Monday nights.
Elliott said he hopes Potter's resignation will help bring calm to the wider community, adding: "We have to make sure justice is served ... Daunte Wright deserves that."
Gannon said on Monday he believes Potter meant to use her Taser on Wright, but pulled out her gun instead, describing Wright's shooting as being the result of "accidental discharge."
At a meeting Monday evening, the Brooklyn Center City Council voted to recommend the firing of Gannon and Potter, which came just hours after it had fired City Manager Curt Boganey.
The council had earlier on Monday voted to confer more powers over the police department to Mayor Elliott, who had called for Potter to be relieved of her duties after Wright's killing.
On the other hand, Boganey, who as city manager has the power to fire police officers, said that talk of firing Potter was premature and that "employees are entitled to due process."
He was ousted just hours later, with Deputy City Manager Reggie Edwards appointed as acting city manager.
