BROOKLYN CENTER, Minn. (NewsNation Now) — Police and protesters faced off once again after nightfall Tuesday following the fatal police shooting of 20-year-old Daunte Wright during a traffic stop.

Hundreds of protesters gathered at Brooklyn Center’s heavily guarded police headquarters, now ringed by concrete barriers and a tall metal fence, and where police in riot gear and National Guard soldiers stood watch.

About 90 minutes before a 10 p.m. curfew, state police announced over a loudspeaker that the gathering had been declared unlawful and ordered the crowds to disperse.

More than 60 people were arrested, Minnesota State Patrol Col. Matt Langer said at a news conference early Wednesday.

Brooklyn Center Police Chief Tim Gannon said Monday that a routine traffic stop, triggered by an expired car registration, escalated into a deadly shooting when officers ran a check on Wright and found an outstanding warrant for him.

Officer Kim Potter, a 26-year veteran, was identified as the officer who shot and killed Wright. Gannon has said he believed Potter mistakenly grabbed her gun when she was going for her Taser. She can be heard on her body camera video shouting “Taser! Taser!”

Potter, who had been on administrative leave, and Gannon both resigned following Wright’s death. A decision on whether prosecutors will charge Potter could come as soon as Wednesday.

Brooklyn Center Mayor Mike Elliott said he was “appreciative” that Potter submitted her resignation but that he had not asked for it nor accepted it. It wasn’t immediately clear what that would mean.

The shooting sparked violent protests in a metropolitan area already on edge because of the trial of the first of four police officers charged in George Floyd’s death.

Forty people arrested at Monday night’s protest, Minnesota State Patrol Col. Matt Langer said at a news conference early Tuesday. In Minneapolis, 13 arrests were made, including for burglaries and curfew violations, police said.

Brooklyn Center is a modest suburb just north of Minneapolis that has seen its demographics shift dramatically in recent years. In 2000, more than 70% of the city was white. Today, a majority of residents are Black, Asian or Latino.

“Whenever, through the line of duty, someone kills another human being, there must be accountability,” Brooklyn Center Mayor Mike Elliott told the “Today” show earlier Tuesday.

Wright’s father, Aubrey Wright, told ABC’s “Good Morning America” on Tuesday that he rejects the explanation that the officer accidentally fired her handgun instead of her Taser.

“I cannot accept that. I lost my son. He’s never coming back. I can’t accept that. A mistake? That doesn’t even sound right. This officer has been on the force for 26 years. I can’t accept that,” he said.

Wright’s family spoke out again Tuesday alongside the family of George Floyd at the courthouse where the trial is being held for a former Minneapolis police officer charged in his death.
