A 15-year-old girl has been arrested on suspicion of sending a threat on Instagram that led to the closure Tuesday of two schools in Carlsbad, police said Wednesday.
The threat led officials, "in an abundance of caution," to close Carlsbad High School and the Carlsbad Village Academy. The teen is a student at Carlsbad High. Classes resumed Wednesday.
Arrested at her home Tuesday night, the student "had neither the means nor the intent to follow through with the threat," Carlsbad police said. The student's name was not released.
"The safety of our children is our top priority," said Lt. Pete Pascual.
Police were assisted by the FBI, a local multi-agency Internet-crimes task force, and the Carlsbad Unified School District in northern San Diego County.
The threat was posted Monday morning, leading to a lockdown at Carlsbad High and then, once police had swept the school, to an early dismissal of classes.
