COEUR D’ALENE, Idaho (AP) — Police stopped a U-haul in Coeur d’Alene Saturday and detained several dozen men who were found inside dressed in khakis, navy blue shirts and beige hats with white balaclavas covering their faces. Authorities said they then arrested all 31 men, whom they believe are members of the white supremacist group Patriot Front.

The arrests occurred near a “Pride in the Park” event.

The back of the U-haul was filled with evidence bags from police. There also appeared to be a homemade riot shield and protective equipment. Videos posted on social media show the men kneeling on the grass with their hands zip-tied behind their backs.

“Reclaim America” was written on the back of one shirt.

Kootenai County Sheriff Bob Norris said: “it appears these people did not come here to engage in peaceful events.”

Coeur d’Alene Police Chief Lee White said “they came to riot downtown.”

White says all 31 were charged with conspiracy to riot, a misdemeanor. The men were going through the booking process Saturday afternoon and are scheduled to be arraigned on Monday. White says those arrested came from at least 11 states.
