Verona, March 17 - Carabinieri police investigating the theft of 17 Renaissance paintings from a Verona museum last November said Wednesday they will not be satisfied until the artworks have been returned to their rightful home. "We are still searching for them, and I will not be happy until I have seen them hanging back in the museum," the head of Verona's flying squad Roberto Di Benedetto said. His comment came the day after Carabinieri arrested 12 people on suspicion of robbing the artworks from the city's Castelvecchio Museum. Seven arrests were made in Italy and five in Moldova. "We believe they are in Moldova, we have a few ideas concerning this possibility," said Carabinieri art squad commander General Mariano Mossa. "The hope is that the paintings are still all together," added prosecutor Gennaro Ottaviano. Investigators believe private security guard Francesco Silvetri, who was on duty at the museum on the night of the theft, Silvetri's twin brother Pasquale and the latter's Moldovan wife Svetlana Pkachuck played a central part in the robbery, acting as an go-between for the thieves. Three armed men broke into the Castelvecchio museum just after closing time on November 17 and before the alarm had been set for the night, stealing canvases worth an estimated 10-15 million euros. The loot included Andrea Mantegna's Holy Family with a Saint, Pisanello's Madonna of the Quail, Peter Paul Rubens' Lady with Campions, and six Tintorettos, Castelvecchio Museum Director Paola Marini told ANSA at the time.
