Authorities are investigating a riot at a juvenile rehabilitation camp in northern Nevada where two buildings were set on fire, four staff members hurt and 10 youths briefly escaped before they were recaptured.
Lyon County Sheriff Al McNeil said Tuesday no one was seriously injured but one staff member at the Silver State Academy in Yerington had to be treated at a local hospital after Saturday night's incident.
McNeil says the state fire marshal is investigating the arson fires and Yerington Tribal Police are investigating the cause of the riot.
McNeil says it's the fourth uprising in four months at the school for at-risk teens. He says he's increasingly concerned about the safety of the community and is pressing school officials to make changes so it doesn't happen again.
