SOUTH SAN FRANCISCO, Calif. (KTVU) - Security will be increased through the rest of the week at 2 high schools in South San Francisco, following possible threats against students and staff.
South San Francisco Police said an anonymous letter "expressed concern and wanted to make officials aware of the possible threats to the campuses" of El Camino and South San Francisco High Schools.
Police have yet to confirm the validity of the threats, but said they wanted to heighten awareness of any suspicious activities.
Both schools will remain open, but parents can keep their children at home, if they notify the school about the absence.
Families received an automated call from the school district alerting them about the letter.
