Monta Vista High School in Cupertino resumed classes Friday morning following a bomb threat that came up empty on Thursday, according to Santa Clara County sheriff's deputies and school officials.

A message on the school's website from Fremont Union High School District Superintendent Polly Bove said that classes were set to resume at 7:35 a.m.

The high school, located at 21840 McClellan Road, canceled classes on Thursday following the bomb threat, Lt. Rick Sung said.

Santa Clara County authorities received a report from San Jose police at 6:39 a.m. of the threat, Sung said.

Police reported a vandalism incident at Lynbrook High School, located at 1280 Johnson Ave. in San Jose, where graffiti there referenced the bomb threat at Monta Vista High School, Sung said.

A specific male teacher, whose name hasn't been released, was referenced in the threat, he said.

Sheriff's deputies and bomb-detecting dogs searched the area and found no explosive devices, Sung said.

Because of its close proximity to Monta Vista High, Lincoln Elementary School, at 21710 McClellan Road, was also closed on Thursday, Sung said.

The sheriff's office is continuing to investigate the incident, Sung said.
