Giuseppe Setola, 38, slid out threw the sewer as police arrived at his home near the southern city of Naples, with officers seeking his arrest as part of an investigation into the killing of six African immigrants in September. The police arrested Setola's wife and seized computers, electronics and surveillance cameras at his home in Trentola Ducenta, about 20km north of Naples. It is not the first time that Setola has managed to escape police. He is wanted over the shooting of six African immigrants and an Italian man on September 18 in the Castel Volturno area near Caserta. The attack has been blamed on the powerful Casalesi clan of the Camorra, with which Setola is linked. Police, security forces and army paratroopers have carried out a number of operations in the region in recent months, arresting seven members of the Camorra mafia in October. They have been accused of murder, criminal association and extortion. Investigators have said they thought the murders could be part of a turf war over drug trafficking, but those who knew the victims have denied they were involved in the trade. The Casalesi clan controls drug trafficking and prostitution in the Caserta area. It has been blamed for dozens of deaths over the past three decades.
