Chicago's top cop has been fired following the shooting of a black teenager.
Mayor Rahm Emanuel announced the dismissal of Police Superintendent Garry McCarthy at a press conference on Tuesday.
"This morning, I formally asked for his resignation," Emanuel said.
It comes after the public's trust in the police department has "been shaken and eroded," he said, adding that McCarthy "has become an issue, rather than dealing with the issue, and a distraction."
"Now is the time for fresh eyes and new leadership to confront the challenges the department and our community and our city are facing as we go forward," he said.
McCarthy, who took over the role in 2011, came under fire after dash-cam footage was released showing Chicago Police Officer Jason Van Dyke fatally shooting Laquan McDonald, 17. The teenager was shot 16 times.
Van Dyke was charged with first-degree murder last week but he bonded out of jail on Monday.
McCarthy had previously said that his involvement in the Van Dyke case was limited.
"The things that I have authority over are training, policy and supervision," he said.
He also defended how the city responded to subsequent protests, calling officers' work "incredible."
