Grant County deputies responded to an injury call at a campground near the Warped event site and when they arrived they encountered several fights as well as burning portable toilets then things turned ugly as some campers pelted deputies with beer bottles, cans and rocks, and the windshield of a fire truck was shattered by debris, according to AP.

10 area agencies were eventually called out to the campground which reportedly held an estimated 4,500 people, many of whom were believed to have been among the 16,400 people that attend the Warped show earlier in the day.

Police arrested five suspects for obstructing a law enforcement officer, disorderly conduct and intimidating a public servant with threats to do harm. The suspects were Jacob Lewis Spaeth, 21, of Fort Lewis; Richard Joseph Dempsey, 27, of Burbank; Kyle Anthony Phillips, 24, of Post Falls, Idaho; Travis William Abram, 22, of Hayden, Idaho; and Aaron David Smith, 18, of Coeur d'Alene, Idaho.

According to AP it took until 5 a.m. Sunday morning for authorities to gain enough control of the area to begin clearing the campground of people.
