In September 2010, police seized a record amount of assets worth €1.5 billion from a Sicilian businessman Vito Nicastri accused of working with Messina Denaro. He had invested in wind and solar energy sources, as a way of laundering money. The Italian police is applying a new strategy to try to capture Messina Denaro, arresting scores of his underlings and seizing millions of euros in assets. "The circle is closing around the No.1 fugitive," Interior Minister Roberto Maroni said. Palermo Chief Prosecutor Francesco Messineo added that the aim of the strategy against Messina Denaro was to "dry up the water he swims in".
