San Francisco’s public schools remained open Thursday after receiving what authorities deemed to be a non-credible threat similar to those sent to other large urban school districts in the U.S. this week.
Five San Francisco Unified School District employees, including a teacher and secretary, received a threat via email at 9:48 p.m. Wednesday, around the same time that Dallas, Houston, Miami, Orlando and Long Beach school employees also received similar threats, Superintendent Richard Carranza said Thursday.
Those threats followed the closure of the Los Angeles Unified School District’s more than 900 public schools and 187 charter schools Tuesday after a school board member received an email that raised fears of another attack like the deadly shooting in nearby San Bernardino. New York schools also received a threat Tuesday but remained open.
The City’s school leaders were notified early Thursday morning of the emails, and contacted the San Francisco Police Department and FBI counter terrorism officials, said Carranza. No specific schools were mentioned in the threats.
Principals searched their schools for anything suspicious around 7:30 a.m. Thursday, and leaders at all 134 schools reported nothing out of the ordinary. Schools opened on time.
“The lack of specificity in the threat, the similarity…to the other threats received across the country led us to believe that this is an at-mass email that was sent out,” Carranza said. “At this point in time, we have no reason to believe that the threat is credible whatsoever.”
District leaders also notified all private and parochial schools in San Francisco, as well as San Francisco State University, City College of San Francisco and all charter schools of the emails.
San Francisco police increased their presence on campuses in response to the threats Thursday as well.
All schools inspected after non-specific email threat. Nothing found. Call 9-1-1 if anything suspicious. School is open.
