DETECTIVES have made a major breakthrough in the hunt for a Unabomber-style terrorist who has left more than 30 people injured during a 12-year campaign in Italy.
Booby-traps have been left in household items such as egg boxes, toothpaste and toys.
Forensic experts have now recovered a pair of scissors from the house of the prime suspect with blades that match the cut of a piece of tape used to fix one device to a bike saddle.
The bomb failed to go off and was recovered intact by police and has provided them with a goldmine of clues.
Detectives recovered the scissors after a search of a house near Trieste belonging to Elvio Zornitta, 49, an engineer, who has been under surveillance for a year.
Mr Zornitta, who has not been formally arrested, yesterday protested his innocence.
He said: "I have nothing to do with any of this."
The original Unabomber, Ted Kaczynski, terrorised the US for 18 years and killed three people before he was eventually caught and jailed for life in 1998.
