Nicholasville Police say they were called to East Jessamine High School Thursday because of concerns over graffiti found in a bathroom.
Police say the words 'May 17 shoot up the school day' were found inside a women's stall.
They say the school notified about the incident.
Nicholasville Police posted a note on its facebook page.
It says, "There is a lot of misinformation going around about the "threat" that was made at East Jessamine High School today. The graffiti that was found on the stall of the women's restroom stated "May 17 shoot up the school day". The School Resource Officer is looking into this. However, the wording and the way it was reported is not specific enough to cause alarm. We take school safety very seriously, and unnecessary alarm does not lead to a safe school environment. We will update you with any new information."
The Police Department says it will step up patrol at the school Friday as a precaution.
