The mother of Europe’s most prolific art thief was in court in France Thursday, charged with throwing away art her son had stolen. “When Mireille Breitwieser, a former nurse, found out that her son Stephane, 33, had been arrested on suspicion of stealing paintings worth tens of millions of pounds from museums across Europe, she rushed into his bedroom and started chopping up all the canvases she found there, prosecutors said yesterday.”
