Taranto, May 24 - Police in the southern city of Taranto confiscated 8.1 billion euros worth of property and goods on Friday belonging to the Riva family, owners of the holding company that owns the troubled ILVA steel plant, as widespread investigations against the Rivas continue. Milan investigators on Wednesday said they are probing Emilio and Adriano Riva for suspected of fraud against the State and fake money transfers. Some 1.2 billion euros transferred out of Italy by the Rivas were also confiscated on Wednesday. Last January, ILVA executive and family member Fabio Riva was arrested in London after two months on the run. Taranto prosecutors issued a European arrest warrant for Fabio Riva, the deputy chairman of parent-company Riva, on December 10 saying that he was sought as part of a criminal probe into the environmental scandal at the facility. Several other top managers have been arrested as part of the investigations. The Taranto plant is the biggest in Europe, and the Riva group is the biggest iron and steel producer in Italy, the fourth-biggest in Europe and the 23rd-biggest in the world. ILVA has been at the centre of a political and legal battle since July when local magistrates ordered the partial closure of its Taranto plant due to serious health concerns. Militari della guardia di finanza stanno eseguendo a Taranto e Milano un sequestro di beni mobili e immobili e disponibilità economiche per 8,1 miliardi di euro nei confronti della famiglia Riva. I sequestri riguardano sia l'Ilva sia la Rivafire spa. Il provvedimento è stato disposto dal Tribunale di Taranto.
