Narrative:

We were cleared for takeoff on runway 36R, captain's leg. At approximately 70 KTS, captain said he thought another aircraft was crossing the runway. Tower called cancel takeoff clearance and I called abort and captain did a low speed abort. Tower told us to exit runway at taxiway F4. Aircraft Y had crossed the runway at taxiway wl and stopped short of taxiway F. Tower said he was not talking to them and they were on another frequency. Tower cleared us to turn sharp right on taxiway F and then aircraft Y started to move also slightly in front of us and turned left on taxiway F. Twice there was a potential incident and at no time did we hear any xmissions to or from aircraft Y. We went back to runway 36R and were cleared for takeoff without further delay.
