A 14-year-old student at Ralston High School has been arrested for allegedly threatening to shoot up the school.

Police say the boy was taken into custody on Tuesday on suspicion of making terroristic threats. Police found no evidence that he intended to carry out his threat. Officials found no weapons.

Ralston Superintendent Mark Adler says the student was acting up in class and made the comments after he was told to go to the office.

Adler declined to comment on the boy’s long-term status at the school.

Ralston is in the Omaha area.
