The Hardin School District canceled classes on Friday while law enforcement officers searched for a teen who reportedly threatened a fellow student with a gun to steal his lunch money. The teen has since been taken into custody.

School officials learned of the attempted theft on Jan. 26. They said they questioned the student and removed him from school, but did not find a gun.

Court records say another student found the gun later that day and gave it to teacher Nora Block. The Billings Gazette reports Block did not immediately turn the gun over to school officials and is charged with evidence tampering and obstructing justice.
