Police in a small Idaho city arrested 31 people allegedly affiliated with a white nationalist group near a Pride parade, authorities announced on Saturday.

People associated with the group “Patriot Front” allegedly had shields, shin guards, and other riot gear with them, including at least one smoke grenade, Coeur d’Alene, Idaho, Police Chief Lee White said. They were charged with conspiracy to commit a riot.

The individuals were arrested after a citizen called police to alert them that at least 20 men were seen getting out of a U-Haul van wearing masks and carrying shields, White said. The group, according to the Southern Poverty Law Center, has white nationalist ideologies that was founded shortly after the “Unite the Right” rally in Charlottesville, Virginia.

The arrests come as the Department of Homeland Security warned last week the summer could be a “dynamic” threat landscape, and extremists could target public gatherings, faith-based institutions, schools, racial and religious minorities, government facilities and personnel, U.S. critical infrastructure, the media and perceived ideological opponents.
