An antique dealer from Holland tried to sell soap on eBay which, according to its owners, was made from the fat of Jews who were murdered in one of the death camps during the Holocaust. The asking price was 199 Euros. As soon as it was posted, the managers of the site took the ad down.
The antique dealer turned himself in to police and gave them two bars of soap to be sent for laboratory testing to see if the claim was true.
