Rome, July 8 - Msgr Nunzio Scarano, the disgraced prelate at the centre of a money-laundering scandal, has been cooperating with prosecutors, officials said Monday. They added Scarano, who was questioned for about three hours on Monday, has provided information that could be helpful in other probes. The prelate was arrested last month on suspicion of planning to elude customs with 20 million euros in cash. He has denied charges that he conspired with a former Italian spy and a financial broker to try to secretly repatriate 20 million euros of laundered money from Switzerland to Italy. At the same time, authorities also arrested Giovanni Maria Zito, an agent in the AISI intelligence agency, and Rome broker Giovanni Carenzio. Police said Scarano and Zito got a private jet to fly back from Switzerland to Italy 20 million euros in cash for a family who were friends with Scarano. Zito is suspected of getting 400,000 euros for arranging cover for the flight. Scarano has been named in a separate probe into receiving money in Salerno near Naples. The arrests have been linked by the Italian media to past probes into alleged irregularities at the Vatican Bank, IOR.
