Expert identified Leonardo work in 2013

(ANSA) Pesaro, February 10 - A lost portrait attributed to Leonardo da Vinci was already examined in 2013 by top Italian art expert Carlo Pedretti who declared it then an authentic work by the great Renaissance artist.
    Pedretti's verdict on the portrait of Mantua Marchesa Isabella d'Este was published exclusively by 'Sette,' the colour magazine published by the Corriere della Sera newspaper.
    Pedretti recounted the recent whereabouts of the painting and published the results of a Carbon 14 test that turned out 95.4% positive.
    Swiss police say the 61cm-by-46.5cm work was in the vault of a Lugano-based trust.
    The painting has been ascribed to Leonardo on the basis of fluorescent analysis dating it to the first decades of the 16th century, they said.
    Further tests will now be carried out to clinch the attribution.
    Police are probing unnamed persons for illegally exporting art works and for insurance fraud, they said.
