Sheriff-patrolLee County Emergency Management Coordinator Steve Cirinna has confirmed that the Iowa Fertilizer Plant construction site in Wever is being evacuated after a bomb threat was discovered Monday.

A press release from the Lee County Sheriff’s Department indicates a message was found Monday afternoon scrawled on the wall of a Port-A-Potty reading: “A bomb will go off tomorrow at 12:00.”

Law enforcement and security searched cars on the way in to the plant and workers reported hours-long delays heading in to work this morning. Around 11 a.m. plant officials evacuated the entire facility. No word yet on whether an explosive device was discovered. The plant’s not yet in operation and no combustible materials are present in the storage tanks.
