An Italian magistrate has issued a warrant for the arrest of Gianluigi Torzi, a key figure in a Vatican real-estate scandal. Torzi was arrested by the Vatican last year and charged with fraud, but a British court last month said that the Vatican’s case against him was marked by “appalling” errors and omissions. In the new warrant for his arrest, the Italian magistrate found that Torzi had undertaken “fraudulent operations”—apparently with the cooperation of the Vatican Secretariat of State.
