There will be increased security at Monte Vista High School in Spring Valley on Tuesday in response to a threatening message found on a bathroom wall.
The Grossmont Union High School District sent a letter to the Monte Vista community Monday explaining the threat and the increased security.
The message included a reference to a possible act of violence but lacked any specifics, the letter said.
The San Diego County Sheriff’s Department is investigating the incident out of an abundance of caution.
The letter said patrols in the area of the school would be increased, as would on-campus supervision.
We urge parents to talk with their student about the potential perils of making any threats of violence. Even a seemingly harmless joke can result in arrest and school consequences,” the letter said.
