wounding one of them. Bidognetti was arrested in November 2008 for attempted murder in connection to the incident. Setola was also said to be responsible for the murder of a gambling arcade owner in a coastal town neighboring Caserta. Setola has been said to have driven a motorbike during some of his alleged hits. Manhunt Setola was accused of masterminding the September 18 drive-by shootings of six West African immigrants in Castel Volturno, which sparked riots and prompted the deployment of 500 soldiers. More than 100 shots were fired during the killings, which were considered among the largest and bloodiest massacres in recent years. Investigators claimed Setola orchestrated the killings to punish the Africans for getting involved in drug trafficking and impeding on the Casalesi clan's business. In response to the killings, Interior Minister Roberto Maroni said the Casalesi clan has "declared war on the Italian state". Police began a manhunt for Setola and the rest of his gang. In October 2008, Oreste Spagnuolo, a member of Setola's alleged killing squad, started assisting police in their mission to arrest Setola and his other accomplices. The next month, police arrested a Carabinieri paramilitary police officer for providing information to Setola about police operations. Franco Roberti, a Naples anti-Mafia police officer, said in November 2008, "Setola is without doubt the brains behind the Casalesi campaign. We are working to flush him out. The circle is closing around him." In January 2009, Setola later sent a letter to a local newspaper denying responsibility for his alleged crimes. He also wrote that he was blind in one eye, a claim that has been met with skepticism by the press, and disputed by police. Setola was eventually found to be sharing a house in Trentola-Ducenta with his wife, Stefania Martinelli, and another suspected mobster. On January 12, 2009, about 50 Carabinieri officers surrounded Setola's hideout in Trentola-Ducenta. As they raided the hideout, Setola and his bodyguard escaped by slipping through a trap door and crawling a mile through a labyrinthine sewer system. The floor and door were secured through a sophisticated locking system, and police said the sewer layout had been "studied very well". Setola reemerged from a manhole outside a dairy, where he robbed a woman of her car and drove away. Police officers and divers eventually chased Setola through the sewers, but did not find him. Martinelli was placed under arrest and questioned
