A frightening message written on a wall in a high school in Idaho has raised fears about the possibility of a mass shooting.
The message, which was written in red ink, was found in a bathroom at Skyview High School in Nampa, Idah,o on April 13, according to the Daily Mail. The graffiti warned that the shooting would occur on April 18 at 10:24 a.m. and be carried out by a gang of 17 students.
"They will target all the teachers and administrators first, then they will kill the students one by one," read the message. "If 911 is called all hell will break loose."
The message concludes by warning, "If you want to survive... stay home!"
An arrow was drawn under the message to indicate the name of one student allegedly involved in the planned shooting. Police and the school have not confirmed whether or not the student had anything to do with the threat, according to KTVB.
"The well-being and safety of the school, our students, and staff is the priority of the Nampa School District and the Nampa Police Department," said Principal Will Barber in a letter to parents.
"We appreciate those who have called to make sure we know about the situation and encourage you to always keep us in the loop if you see or hear anything that concerns you," he wrote.
Sgt. Jason Cantrell said that the police department will work with the school district to investigate the threat, KBOI reports. Cantrell added that the school would have additional security provided by the police on April 18.
Kathleen Tuck, a spokeswoman for the school district, said that police and school officials are looking into security camera footage to find out who made the threat. Tuck added that the message had been shared on social media, and worried some parents who saw it.
"Student safety is our number one priority," said Tuck. "We would never put the students in an unsafe position."
