Florence, November 12 - Italian police said Monday that they had arrested a new suspect for alleged involvement in the Mafia bombing campaigns of the early 1990s. Cosimo D'Amato, a 47-year-old who used to be a fisherman, is suspected of supplying Cosa Nostra with large quantities of TNT which he recovered from World War II remains. It is believed the explosives were used in bombings in 1993 and 1994, including a 1993 blast in Rome's Via Fauro in which no one was killed, and the failed attempt to set off a bomb at the city's Stadio Olimpico in January 1994. TNT was also used in the 1992 bomb attack that killed anti-mafia judge Giovanni Falcone, his wife and three of his bodyguards. The explosives are thought to have been supplied to a Mafia gang set up for the bombings by the boss Francesco Tagliavia. D'Amato is a relative of Cosimo Lo Nigro, who was one of the people to have been convicted for the bombing campaign, which also claimed the life of Falcone's friend and fellow anti-mafia judge Paolo Borsellino.
