Ralston Police are investigating a bomb threat sent to Ralston High School this morning.
School administrators say they received an anonymous and vague bomb threat in an email. The school immediately called police who did a walk-through of the building to make sure it was safe.
The school says preliminary research indicates the sender of the email is likely connected to national hoaxes that took place on the east and west coasts last year.
The school is operating as normal.
