The Volusia County School Board postponed its Tuesday night meeting after the district received information from law enforcement about a possible threat, creating a public safety issue.
According to the school board, the meeting was scheduled to begin at 4 p.m. before the district received information that "warranted the postponement in the interest in public safety."
On Wednesday, deputies released a 911 call placed by the organizer of a planned protest.
"I just received via Facebook what I consider to be a threat," Rick Sarmiento said. "It says, 'You live by the sword, you die by the sword.' I consider that to be a viable threat."
One of the items slated to be discussed at the meeting is a controversial history book that teaches Islam entitled "World History." Critics say the book focuses too much on the pillars of Islam and that a religion that allegedly calls for the demise of America shouldn't be taught to students.
The cancellation was announced to the crowd after the Department of Justice received notice of the threat and board members had been escorted away from the meeting room by security.
It's not yet known when the meeting will be rescheduled.
The textbook also sparked controversy in Brevard County earlier this year.
