Caldwell police are working to find out who's responsible for rattling nerves at the Caldwell Public Library and the surrounding area Tuesday night.
Police said they were called to the library, at 1010 Dearborn St., shortly after 7 p.m. A bomb threat written in pencil was discovered on one of the wood chairs in the northwest corner of the building, officials said.
The library and surrounding businesses were evacuated, and nearby roads were shut down. Police said the library was cleared by a Nampa bomb dog and his handler.
Police did not have a suspect, and they were reaching out to the public for help in identifying who made the threat.
Anyone with information is asked to call Caldwell police at 455-3115 during regular business hours, or 454-7531 after hours.
