LINCOLN, Neb. (AP) — Three state employees and three teenagers were briefly hospitalized earlier this week after an outbreak of violence at a state-run juvenile facility in Kearney.

Department of Health and Human Services spokesman Russ Reno says five youths are accused of assaulting staff members Tuesday night at the Youth Rehabilitation and Treatment Center. Reno says youths damaged ceiling tiles, sprinkler heads and doors in the room where they were being held.

Three youths were hospitalized after they allegedly broke into a staff office and ingested an employee’s diabetes medication.

Mike Marvin, president of the Nebraska Association of Public Employees, says one staff member was bitten and had teeth damaged in the assault. Reno says only one of the youths was held overnight for observation. The others were treated and released.
