BUCYRUS, OH (WCMH) — A bomb threat received by Bucyrus City Schools turned out to be a hoax.

The district was already planning for a two hour delay because of slick roads when the threat came through on Twitter at 4:53am on Thursday. The threat has since been removed from the website.

All school buildings in the district were closed at 7am. All of them were given the all-clear by noon.

“I want to assure our parents, students and staff members and the Bucyrus community that our school buildings are safe and secure,” said Superintendent Kevin Kimmel.

K9’s from Ohio State Highway Patrol, Allen County and Columbus Fire swept through all three district buildings this morning.

Bucyrus Police Chief David Koepke said whoever’ behind the hoax will face at least a felony charge.

“It’s at a minimum inducing panic and it was just a terrible thing and we will not take it lightly,” he said. “We will investigate it until the end.”

Superintendent Kimmel said not only did students lose out on a day of class, the district also took a financial hit.

“At this point a daily cost to the district is about $30,000 in lost salary and benefits for today, a district our size,” he said. “Not counting the loss in income from food service and some of the other related costs.”

Bucyrus Police will continue to investigate. Their focus is set on prosecuting whoever made the fake threat.

“We’re going to be reaching out to homeland security and the other agencies that have the ability to assist us so that we can do the best job possible,” he said.

All after-school activities have been cancelled.
