A major southern Kentucky facility had to be evacuated Wednesday morning after a bomb threat.

Police say someone called the Center for Rural Development in Somerset overnight and left a message saying a bomb was in the building.

An employee at the center heard the message around 9:30 Wednesday morning and called police.

The entire building was evacuated as a precaution. Police conducted a sweep of the building, but didn't find anything suspicious.

The building is back open now. It houses several federal and state agencies.

There's no word on where the threat came from.
