Narrative:

Traffic was moderate to heavy. I had small aircraft X over the landing threshold, touching down when I observed an aircraft crossing the runway downfield. The arrival was on the runway and slowing down before the aircraft cleared the runway. I asked ground what happened and received no reply. I did not at any time approve the crossing. No action was taken concerning this situation. It was not conceivable to have the small aircraft X go around at time of occurrence. The controller in charge at time of the occurrence did not feel the situation warranted action. I later found out that the pilot of the aircraft which had permission from ground control to cross was also upset as he noticed the small aircraft X rolling out on the runway. The following day he advised the controller in charge that he was going to file a report re: the incident.
