The school said Wednesday that it increased police presence around the campus in Richmond, KY.
Officials say classes were canceled midmorning Wednesday on the campus of about 16,000 students.
The school says there's no evidence of imminent danger but reported an escalating threat, originating from social media.
On Monday, campus police issued a public safety alert after a threat was found in a campus bathroom. The graffiti said: "Kill All By 10/8/15."
The action comes in the wake of a recent shooting at an Oregon college. The shooter killed nine people and himself.
