Quebec authorities say they found no human remains in a swastika-stamped bar of soap sold at a Montreal curio shop whose owner claimed it was made with fat from Holocaust victims.

The soap — and the seller's claims — sparked uproar from Montreal's Jewish community in March, when its existence was revealed by CBC News.

At the time, the St-Laurent Boulevard shopkeeper said the soap was rendered from remains of Jewish prisoners held in concentration camps during the Holocaust 70 years ago.

The shopkeeper — who is Jewish — said he obtained the soap from a soldier who served in the war.

Montreal police sent the soap to an Ontario laboratory for DNA testing, and results concluded the bar contained no animal nor human remains.

The shop owner likely won't be charged with fraud for misrepresenting his soap, police said.
