The Liberty High School in North Liberty is quiet today.
Teachers and parents were notified last night that classes at the new facility were cancelled due to a threat.
Administrators notified parents on the Iowa City School District website that they received a credible threat to "shoot up the school," which mentioned students by name as targets.
North Liberty Police say they arrested the minor responsible for the threat around 9:30am Friday.
With the suspect in custody, school officials said they'd open Liberty High back up for extracurricular activities today.
