Authorities say they've detained a student at an eastern Iowa high school who covered his face with a mask and brought a knife to school. The Johnson County Sheriff's Office says it received a report Monday about an intruder attempting to enter Lone Tree High School in Lone Tree. Deputies arrived at the school and found staff detaining an 18-year-old student. Police say he had been wearing a Halloween-style mask and was in possession of a knife. The school was put temporarily on lockdown. The student was placed into custody and taken to the University of Iowa Hospitals and Clinics for evaluation.
