A 15-year-old Pulaski County boy was arrested Monday after police said he sent text messages threatening to attack Southwestern High School in Somerset.
The student, who was not publicly identified, sent messages to another student threatening to "detonate fire bombs and shoot up the school," according to a news release from the Pulaski County sheriff's office.
The texts contained specific information about where the bombs would be placed and the time frame when they would be detonated, but no date was given.
Sheriff's deputies began investigating Monday, and they said the student admitted sending the texts.

The boy "could not explain to investigators why he sent them or suggest a motive for the threats," according to the release.
The student was charged with first-degree terroristic threatening and was taken to the Adair County Juvenile Detention Center.
