Narrative:
I was the local controller for the following event. Aircraft X had been cleared to land. As he approached the runway; aircraft Y called up ready for takeoff. I responded by saying 'aircraft Y; lexington tower; roger.' after a minute or so later as I was scanning the runway I noticed that aircraft Y had begun taxiing on to the runway in front of aircraft X who was now very short final. I immediately issued go around instructions to aircraft X to avoid a collision. At the point of go around aircraft X was less than 100 ft AGL and within 1/8 of a mile of the landing threshold.

I responded by saying 'Aircraft Y; Lexington tower; roger.' After a minute or so later as I was scanning the runway I noticed that Aircraft Y had begun taxiing on to the runway in front of Aircraft X who was now very short final. I immediately issued go around instructions to Aircraft X to avoid a collision. At the point of go around Aircraft X was less than 100 ft AGL and within 1/8 of a mile of the landing threshold.
