SAN DIEGO, CA — Lockdowns have been lifted at two San Diego schools after an active shooter threat was deemed unfounded, authorities said.
Clairemont High School was placed on lockdown Monday morning after police received reports of a potential threat against the campus at 4150 Ute Drive, according to the San Diego Police Department. Out of an abundance of caution, police also locked down nearby Marston Middle School at 3799 Clairemont Drive.
Officers conducted a sweep of both schools before lifting the lockdowns, first at the middle school and later at the high school.
