Three campers were arrested on Friday night on charges of assaulting a Colorado State Park Ranger at Loveland's Boyd Lake State Park.

43-year-old Troy Dale Rael, 45-year-old Noah Moses Rael and 18-year-old Nathanial Troy Rael were booked into the Larimer County Jail, according to a county sheriff's press release. All three men are charged with second-degree assault and obstruction of a peace officer.

The incident began around 10:15 p.m. when a park ranger gave a verbal warning for excessive noise to a group of 10-15 people that were reportedly drinking heavily at their campsite.

The ranger later returned to issue a formal warning after the group failed to comply.

A physical altercation broke out when the ranger asked Troy Rael for identification. As the ranger attempted to take him into custody, the other individuals became involved in the altercation — the ranger was reportedly struck in the head several times.

The ranger drew a taser to get away from the assault.

Larimer County Sheriff’s Office deputies and Loveland Police officer were then dispatched to the scene.

All suspects are innocent until proven guilty in the court of law. An arrest is merely an accusation of a crime by law enforcement.
