The threat — the nature of which was not disclosed — was made against Carlsbad High School via the social networking service Instagram, according to school district officials.
About 10 a.m. Monday, teachers were directed to secure all students in their classrooms at the Monroe Street campus, district officials said.
Students were kept locked inside for a little over an hour as officers performed a sweep of the grounds and buildings, finding nothing hazardous. At 11:15 a.m., campus administrators released all students for the day as police continued to investigate.
Early Monday evening, Carlsbad Unified School District Superintendent Suzette Lovely announced that Carlsbad High and Carlsbad Village Academy would be closed Tuesday as an “added safety measure” and “in an abundance of caution.” It was unclear why the second school was included in the precautionary action.
Carlsbad Village Academy is the district’s continuation high school.
All other district schools were to be open and operating as usual, Lovely stated in a message on the high school’s website.
