Kent Lovern, the chief deputy district attorney in Milwaukee County, said in an email Wednesday morning that “no charges against anyone in this incident have ever been referred to this office.” Mr. Lovern said he had not seen the video.
Milwaukee, which has overhauled leadership of its police department in the months since Mr. Brown’s arrest, has previously struggled with relations between the police and its residents. In 2016, when an officer fatally shot a man who was fleeing, the city experienced two nights of unrest. The officer was acquitted in 2017.
On Tuesday, with word circulating that release of the video was imminent, Chief Alfonso Morales released a video asking for trust in the department and pledging transparency when officers commit misconduct. Chief Morales took over as the department’s interim leader in February, about three weeks after Mr. Brown’s arrest, and was named chief in April. He replaced Edward A. Flynn, whose 10-year term as chief included struggles with high homicide rates and strained community relations.
“If there’s ever an incident where one of our members makes a mistake, unnecessarily escalating a situation, I’m going to be honest and transparent about it,” Chief Morales, a 25-year veteran of the Milwaukee police, said in the video. “In those instances where we have made mistakes and are wrong, I’m sorry.”
The episode in Milwaukee also was one of several recent encounters in which police officers were recorded using force to subdue a professional athlete.
In 2017, Michael Bennett, then of the Seattle Seahawks, was taken to the ground and handcuffed by the police in Las Vegas.
Months later, video captured a violent encounter between Georgia police officers and Desmond Marrow, a former N.F.L. player.
Mr. Marrow, who was accused of participating in a road rage incident, was seen on the video being forced down by three officers. Mr. Marrow said, “I’m not even fighting back” as he was thrown to the ground.
