Update: Controlled access at Pocatello/Chubbuck schools over

Update 4:30 p.m.: According to the school press release, a teenage boy called the Alameda Middle School and threatened to be violent at a school.

Staff was able to trace the number back to a 6th grade student. Police took the student into custody for questions. Officers learned that a group of students had been making prank calls earlier that day. That is when one of the students thought it would be funny to make a prank call to the school.

The controlled access was lifted once officers determined the person they were talking to was responsible for the threat.
