Students were evacuated following a bomb threat at a middle school in Easton.
Officials at Helen Keller Middle School say graffiti was found on a bathroom wall around 11:15 a.m., threatening to bomb the school.
Easton police say they ordered students evacuate to the Easton Community Center, located across the parking lot from the school.
Police searched the school building for around two hours. They say they brought in police dogs to sweep the building but found nothing.
Students returned to their classrooms after an all-clear was given.
Easton's school superintendent sent out emails to parents throughout the incident and afterward, praising the evacuation as "a model of safety and community spirit."
