Milan police squad chief Alessandro Giuliano said Monday that three of the six had held one of Berlusconi's closest advisors hostage for 11 hours in his home last month until he reached Berlusconi by phone to demand the money.
Berlusconi's attorney, Nicolo Ghedini, told reporters he spoke to the hostage-takers that day and refused to give them any money until he saw the documents.
Apparently that's all that was needed to free Berlusconi's treasurer, Giuseppe Spinelli. Police later identified the ringleader by his red and black sneakers - colors of his favorite team AC Milan, which Berlusconi owns.
