Looting inside downtown businesses occurred after the shooting, Elder said, but no details were available. Officers were beginning to make arrests, he said. Videos posted to social media appeared to show people smashing windows and breaking into businesses to steal merchandise.

Mayor Jacob Frey pleaded for everyone to go home during a news conference. He imposed an immediate curfew and requested assistance from the National Guard.

“What we’re calling for right now is peace,” he said. “This destruction and property damage just takes away from that underlying goal.”

Police Chief Medaria Arradondo dispelled misinformation that his officers were involved in the suicide death, saying it was not officer-related.

“I will not allow to add more trauma to a city that’s still grieving from May 25,” referencing the death of George Floyd, whose death while in Minneapolis police custody sparked ongoing nationwide protests and riots.

He said one officer was injured, but not seriously.

Hennepin County Sheriff David Hutchinson told reporters downtown that deputies were assisting the Minneapolis Police Department. He urged people to go home and obtain the facts of the case before jumping to conclusions about what happened hours earlier.

“When the police do things wrong we need to hold them accountable, but this is not the case,” he told reporters. “We as the police, the Sheriff’s Office did nothing wrong tonight.”

Gov. Tim Walz declared a peacetime emergency Wednesday night and said the National Guard and 150 Minnesota State Patrol troopers were being mobilized to assist local law enforcement.
