SALT LAKE CITY (AP) — The “No Kings” protest in Salt Lake City was struck by violence when a man allegedly brandished a rifle near the crowd, prompting a volunteer for the event to fire three shots, hitting the man and a protester who later died, according to police and event organizers.

Arthur Folasa Ah Loo was a former contestant on “Project Runway,” whose designs were beloved by celebrities from “Real Housewives” to “Moana” star Auli’i Cravahlo.

Police officers in major cities suffered injuries at the hands of violent agitators over the weekend, with several rioters throwing fireworks and other objects at the officers

The fashion designer was among 10,000 protesters who occupied downtown Salt Lake City for the “No Kings” protest.

And police told crowds at a rally in downtown Los Angeles to disperse after authorities said people had thrown "rocks, bricks, bottles," and "fireworks" at officials. Activists in some areas braved wet weather to raise signs and chant slogans.
