OKLAHOMA CITY -- A 14-year-old John Marshall High School student could be expelled for typing a bomb threat during computer class.

Last Wednesday, another student found a document titled "Urgent" saved on a school computer.

The letter warned that a bomb was in the building and would go off if his demand wasn't met. His demand was going to be announced on the PA after school.

In the letter the teen wrote "If my demands aren't met I will not tell the location of the bomb and all the students and teachers, etc. will die! It's set to go off 10/14/09 at 2:00! You have been warned!"

The student was released to his parents and his name was not released.

According to the police report, a long-term suspension hearing is set for this week.
