Police are trying to track down the person or people responsible for a bomb threat that forced the evacuation of the Danville High School Wednesday morning for several hours. The bomb threat was found by a staff member on a bathroom wall in the high school. Students and staff walked to the nearby Danville Primary School while state and local police responded to search the building. Abigail Thomas, a freshman at Danville High School, says the ordeal was frightening. Police wouldn't reveal exactly what the note said due to the ongoing investigation. Superintendent, Dr. Jason Bendle, says the students and staff did a good job with the evacuation.
