CARLSBAD, Calif. – Both Carlsbad High School and Carlsbad Village Academy campuses remained closed Tuesday in response to an anonymous online threat.
The decision was made out of an abundance of caution as the investigation continues after the threat was made Monday via Instagram.
Lost class time will likely be "made up" later in the school year.
Students and faculty were told to "shelter in place" at Carlsbad High School Monday at about 10 a.m. after officials were notified of an anonymous online threat, school district official said.
Several police officers responded to the high school located at 557 Monroe Street to investigate a threat posted to Instagram, Carlsbad Unified School District spokesman Rick Grove said.
A parent told school officials a threat to "shoot up the school" was posted on Instagram, Grove confirmed.
Students were held in their secured classrooms while police searched the campus.
"It was kind of hectic, no one knew wCarlsbad Village Academyhat was really going on, it happened really quick," said Chris Talabrese, a Junior at the school.
At 11:15 a.m., campus administrators released all students for the day as police continued to investigate. The school will remain closed Tuesday pending the results of the investigation, according to Carlsbad Unified School District officials.
