The Jackson campus of Salmon Arm Secondary was evacuated on Tuesday after a possible bomb threat.
A passerby noticed a note scrawled on the wall of a pedestrian underpass near the school and police were alerted.
The note itself made no mention of specific people or places and it is unknown when the message was written.
However the Salmon Arm RCMP decided to err on the side of caution and all students were moved to the Sullivan Campus away from the school.
A police dog was called in, but nothing was discovered.
RCMP continue to look for the individual.
