An arrest has been made after an anonymous threat posted to the popular phone app called “Burn Book," police said.
At approximately 12:40 a.m. Wednesday, a message threatening the safety of students and staff at the El Cajon Valley High School was reported.
When school staff and El Cajon police were notified, police posted a heightened presence on campus.
Police later arrested a person at a nearby middle school responsible for posting the message, police said.
That 8th grader did not have a known connection to the high school, police said, and they did not believe there was any danger to anyone at either school.
The student was booked into Juvenile Hall on charges of Criminal Threats.
Early Wednesday, San Diego County Sheriff’s Department officials were investigating a different threat posted to the same application that allegedly made threats of violence toward Mission Hills High School in San Marcos.
Officials said the possible internet threat – which is still unsubstantiated at this point – was discovered by a MHHS student on the website BurnBook.com at around 10 p.m. Tuesday.
