I stole a Dibella statue from a Argonian(dont know the name of his and place) who slept in some island at far north.He didnt saw me but one day,I walked near Markath and these thugs attacked me and reason was this theft when I read a letter.And these attack repeated again,again,again.....Finally I have enough of this I came back to that island and killed that slimy lizard just for revenge.But these attacks ended :D But glitch should be he didnt saw me and send a thugs to "teach me a lesson".
