You can just talk to an npc with an different char than the person which has stolen goods in it's inventory. Rob him with another char while he/she is still talking. Run away, - Quit the talk screen if your second char is away far enough and let the npc accuse you of stealing. If you have no stolen items in your Inventory you don't have to pass a speech check and all is good.
Afterwards the npc will search the near area for aound 10 seconds and than returns to his usual spot and won't search again for stolen items. You can repeat this as many as you like if you just create a new char afterwards. Which means: Everytime the merchant inventory resets you can rob him again.
Edit: That is btw the most obvious reason why some ppl bragging how easy tactician is. They just exploit this and running around with epic equip worth ~40k per lvl up which is in a normal game unobtainable.
