PHOENIX (AP) — More than 5,000 people gathered last weekend in the Tonto National Forest northeast of Phoenix for an illegal party that was broken up by U.S. Forest Service personnel, according to authorities.

The Tonto National Forest requires a permit application to be submitted and approved for all gatherings of over 75 people.

Officers patrolling in the Sycamore Creek area Saturday night came across the unauthorized gathering.

According to Phoenix TV station KPHO, forest officials say campers and partiers restricted access by taping off sections of the main road to designate the party area and vehicles were parked all along the main roads.

Authorities said violations included DUI, double riding, speeding, reckless vehicle operation, staging camps in illegal areas, blocking roadways, illegal use of fireworks and target shooting.

By the end of the night, there had been seven vehicle accidents reported and multiple reports of stolen off-highway vehicles.

Authorities said one person was taken to the hospital after getting injured when two quads collided.
