Wake County Schools told ABC11 they found explosive materials on the Sanderson High School student, but it was a smoke producing chemical and not something considered a bomb.
A search warrant shows that Tuesday a student at Sanderson High School told staff members that another student had given her a smoke-producing chemical.
The message to parents said that a total of five students had obtained the chemical from the student.
Police would not go into detail about what that explosive device entailed, but said under some circumstances the substances could become explosive.
Wake County Schools said students were not in any danger and sent a message to parents letting them know what happened.
The 15-year-old student, who is only referred to as J.E. in search warrants, is being processed through the juvenile justice system.
The school is still in the process of determining what disciplinary action he faces.
