Five staff members at the Campus at Lookout Mountain, a collection of three juvenile detention centers in Golden, were injured last week while responding to a series of riots inside the facilities, according to police.

The violent uprising took place across three days, Feb. 10-12, Golden police said.

At least two employees were hospitalized with injuries while trying to intervene as three young people threw televisions and other items at glass windows inside a pod, police said.

The Division of Youth Services, which oversees Colorado’s 14 youth detention facilities, said a “small number” of youths sustained minor injuries during the riots. They were treated and returned to their living units the same day.

On Feb. 10, someone intentionally pulled a fire alarm, allowing multiple teens to exit the buildings and run through the interior of the complex, police said.

“Many were noncompliant with staff and officers,” Stephanie Sipes, a Golden Police Department spokeswoman, said in an email.

One youth brandished a small homemade weapon and got into a physical altercation with a staff member, police said. The situation eventually calmed down, and all the young people were escorted back to their buildings. No injuries were reported in that incident.

One teen was arrested and charged with a litany of offenses, including second-degree assault and menacing.

Two days later, one teen became physical with the staff and another kicked out a door window before damaging property, authorities said. Three staff members were injured trying to intervene and detain the teens.

Lookout Mountain used to house four separate detention centers, but the state closed one this month because of low numbers of staffers and youths.

In 2019, there were five high-profile security issues at the Golden complex, including a staff member arrested on suspicion of possessing child pornography, escapes by violent juveniles and a riot between rival gangs, which injured three staff members.

The following year, the state split up Lookout Mountain into four distinct facilities, following evidence from other states that shows better outcomes at smaller centers.
