Something similar happened to me; killed some thalmor who were leading a prisoner across the plains around Whiterun. Managed to kill all of them (even the prisoner, who started to attack me as well). Message appeared saing "all witenessed killed. Bounty reduced to 0" or something to that effect. Walked into Whiterun only to be immediately attacked by guards. Solution: Exit cell, and walk casually up to guards. (note: both times I had my weapon sheathed). They should initiate a conversation. Hopefully.
Also: did you not kill anybody? Steal anything? It sounds as if you didnt, and if so could be down to a bug/glitch. (that word is tossed around a lot on this forum......)
