Bomb threat leads to hours-long lockdown at two South Bay schools

NATIONAL CITY (CNS) – An anonymous email claiming that a bomb had been
planted at one of two neighboring South Bay public schools prompted lockdowns
at the campuses Tuesday, but a police investigation did not turn up any hazards.

The apparent hoax threat prompted the security alerts at Olivewood
Elementary and Sweetwater High in National City shortly after 9 a.m., said
Nadege Johnson, a spokeswoman for Sweetwater Union High School District.

Administrators kept all students secured in their classrooms or on
school playing fields while authorities sought to determine if any hazards
existed at either campus, according to police.

The search at the primary school was complete by early afternoon with
nothing dangerous found, but the lockdown there remained in effect as officers
with service dogs continued looking over the grounds and checking rooms at the
campus immediately to the south, district officials said.

Police gave an all-clear for Sweetwater High shortly after 2 p.m.,
according to Johnson.

It was unclear who sent the threatening email, which was received by
several staff members at the secondary school, authorities said.
