Early reports say students and staff at Zeigler-Royalton High School were moved to the elementary school after a message was found around 8:30 a.m. that was written on a bathroom wall saying there were two bombs located in the building. Parents were quickly notified they could pick up their children at the elementary school gym.
After the school was evacuated, the bomb squad was called in, but the search turned up no explosives.
The Ziegler-Royalton bomb threat comes one day after a bomb threat was made to Franklin Middle School in Salem.
Neither a sweep by officers, nor a sweep by a Secretary of State Bomb sniffing dog, revealed explosives or suspicious materials Thursday at the Salem school.
A handwritten bomb threat was found by a teacher early Thursday morning, which resulted in police being called and students eventually being dismissed for the remainder of the day.
As Franklin Park was given the all clear Thursday, regular classes and schedules resumed Friday.
Law enforcement officials have indicated they believe the threat could have been a prank by a student.
