Happened to me when I come the place they first arrested you.
This time I fight and survived, and killed the last witness, each came to nowhere because other guards demanded the "bribe".
I refused, they attacked me, I reloaded the game just after I killed the other guards and the game worked normal again, nobody trying to arrest or kill me.
See.
Doesn't means that this is a solution, only this solved (or appears to be) to me at moment.
