Bonners Ferry High School was evacuated Tuesday morning due to a bomb threat that never materialized.

According to Boundary County School District Superintendent Dick Conley, a custodian found a note in the girl's bathroom that said, "Bomb. 3:30."

The students were moved to Boundary County Middle School, Conley said.

Police searched lockers, backpacks and classrooms and a bomb-sniffing dog searched the inside of the school as well as around the school grounds and found nothing.

Students were let back into the building at 2 p.m. The school will be on normal operating hours Wednesday.
