OKLAHOMA CITY (AP) _ An eighth-grader's Internet note threatening students and teachers at the Classen School of Advanced Studies is under investigation by Oklahoma City police.
The note also threatened harm on the school, according to a letter sent home Friday to parents of Classen students.
District spokeswoman Sherry Fair say police and the district are investigating the situation.
Fair says a male eighth-grade student at the school made the threatening Internet post.
A district employee whose child attends the school discovered the online message.
The family contacted the school's administration Friday.
School administrators say it will be safe for students to return to class Monday.
