The Grandview Heights Public Library was evacuated for about three hours Friday, April 18, due to a bomb threat.

Nothing was found during a three-hour search of the building by the Franklin County Bomb Squad using bomb-sniffing dogs and a robot.

Library employees were allowed back into the building to gather their belongings about 5:40 p.m. April 18.

An anonymous caller contacted Columbus police about 2:40 p.m. and said two explosive devices were in the library, Grandview officer Ryan Starns said.

Columbus immediately contacted Grandview police and the bomb squad was called to the scene, he said.

Police closed First, Oakland and Ashland avenues near the library. Grandview police contacted the Grandview Heights City School District to request that students be diverted away from the library as they left for the day, said Hayley Head, executive assistant to the superintendent.

The district complied with the request, she said. The library was open as usual Saturday, April 19.
