A Julian High School student was under investigation Friday for possibly making a threat against the East County campus.
Sheriff's investigators questioned the teen — whose name, age, gender and grade level were withheld — in an undisclosed location off campus, according to school spokeswoman Yvonne Fleet.
"At no time were our students or school in danger," she said. "We understand that this can be unsettling for students and parents alike and want to assure the community that we take all threats seriously and work closely with law enforcement to ensure the safety of our schools."

Authorities did not disclose the nature of the possible threat.
Four San Diego-area youths have been arrested over the last several weeks amid a spate of direct and veiled school-violence threats that have erupted nationwide in the aftermath of last month's gun massacre at Marjory Stoneman Douglas High School in Parkland, Florida.
