CUPERTINO (KCBS) – Two Cupertino schools have been declared safe by Santa Clara County sheriff’s deputies Thursday morning after a search following a bomb threat came up empty, a sheriff’s lieutenant said.

Monta Vista High School, at 21840 McClellan Road, and adjacent Lincoln Elementary School had canceled classes for the day because of a bomb threat early Thursday morning, Lt. Rick  Sung said.

The all-clear was given at about 11:10 a.m. after bomb-detecting dogs found no explosive package or device, Sung said.

Graffiti spray painted outside Lynbrook High School in San Jose made reference to killing a specific teacher at the Cupertino high school, said a spokesman for the Santa Clara County Sheriff’s Office.

KCBS’ Matt Bigler Reports:

Police did not disclose the name of the teacher.

Classes were not canceled at nearby Kennedy Middle School.

Several intersections around the campus as a precaution have since re-opened.
