LARKSPUR, Calif. - Authorities canceled classes at three high schools Thursday in Marin County because someone called in a threat, schools officials said.
What we know:
Redwood, San Andreas and Tamiscal high schools, all in Larkspur, were evacuated due to a safety concern, according to the schools' websites. All athletic events and the open house scheduled at Redwood on Thursday were postponed.
In a Nixle alert, Redwood High said that the staff got a voicemail at 8 a.m. indicating there might be a possible threat on campus.
The alert was not more specific than that.
Staff immediately contacted the Central Marin Police and "out of an abundance of caution," the decision was made to cancel school and close the campus.
Why you should care:
"This is not funny at all, this is a felony crime," Central Marin Police Capt. Hamid Khalili told KTVU. "And because of the inconvenience to school, all the families, the resources dedicated to resolving this incident, this is very serious. "Those individuals will be held accountable and we will charge them to the fullest extent of the law."
Police officers were seen peeking into cars parked on campus, looking inside the windows. A group of firefighters were also called out to investigate.
Officials did not report finding anything suspicious during their visit, though police said this was the second school threat this school year.
All schools are expected to re-open on Friday.
