KIRTLAND, Ohio - School district officials ordered buildings to be closed Wednesday while authorities investigate a bomb threat that was written on a bathroom stall at the high school.
The message, found last week, indicated a plan to bring a bomb to Kirtland High School on May 10, said Stan Lipinski, school superintendent in this city about 20 miles northeast of Cleveland.
"We talked to police, met at the end of last week and decided to put extra security practices in place," Lipinski said.
Police used dogs to search the school Tuesday morning, with nothing suspicious found. A camera was installed Sunday in the area where the threat was discovered.
A letter from the superintendent explaining the situation was sent home with students Tuesday.
Police Chief Wayne Baumgart said he was "reasonably certain" the threat was a prank, but officials have continued to investigate.
The district's three schools sit on the same campus and have an enrollment of about 1,150 students.
Lipinski said he was optimistic that the schools would reopen Thursday.
