LINCOLN, Ark. (AP) - Authorities in northwest Arkansas say a student has been arrested in a threat against a high school that prompted a brief lockdown.

Lincoln High School was under lockdown for about 15 minutes Thursday after a male student threatened to kill "everybody in the school."

Lincoln Police Chief Russell Morphis told Fayetteville television station KHOG (http://is.gd/EWqQu3 ) that the boy was charged with terroristic threatening.

Lincoln school Superintendent Clay Hendrix says parents weren't notified because the lockdown was so brief.
