A person of interest was taken into custody Saturday night during a “No Kings” protest in Salt Lake City, Utah, according to police.

Salt Lake City Police said one person was injured in the shooting, which happened near 200 South State Street. The victim was transported to a hospital with life-threatening injuries.

Police urged demonstrators to leave the area in an orderly fashion. Police said the shooting was “possibly associated” with the protest.

The situation remains “fluid,” police said.

Utah Gov. Spencer Cox, a Republican, said the shooting is “deeply troubling.”

“The shooting at tonight’s protest in Salt Lake City is a deeply troubling act of violence and has no place in our public square,” Cox wrote on X. “This is an active situation, and we’re working closely with law enforcement to ensure accountability.”

A group of about 10,000 people marched between Pioneer Park and the Federal Building before the shooting on South State Street.

“No Kings” demonstrations rolled out in cities across the country on Saturday to protest President Donald Trump. Participants shouted anti-authoritarian chants and voiced support for protecting democracy and immigrants rights. The demonstrations came on the same day as the roughly $45 million military parade in Washington, D.C., to celebrate the Army’s 250th birthday and Trump’s 79th birthday.
