Heritage High School was locked down for two hours Tuesday afternoon after a receptionist received a phone call threatening a bomb.

Clark County sheriff’s deputies searched the campus while students remained in a shelter-in-place response, but found nothing suspicious.

The phone call came in about 1 p.m. Tuesday, prompting the lockdown and law enforcement’s response to the school, 7825 N.E. 130th Ave.

Deputies set up containment and swept the campus, but ultimately did not find anything suspicious.

“The threat they were looking for was outside the building,” Evergreen Public Schools spokesman Kris Fay said. “That’s where (deputies) were doing their initial sweep. When they were done with that, they also checked the interior of the building.”
