The head of the Caltanissetta
flying squad, Marzia Giustolisi, received a bullet in the post
on Tuesday.
The envelope containing the bullet also contained threats,
police said.
It is the second such Mafia warning in Caltanissetta this
month.
On October 11 a prosecutor in the central Sicilian city also
got a bullet through the post.
The envelope containing the slug was sent to Caltanissetta
Chief Prosecutor Amedeo Bertone.
"I will not stop, I'll go on with my work, with my whole
office," Bertone told ANSA.
The magistrate is is working on various cases including the
so-called "Montante system" named after the former head of
Sicilian industrial federation Sicindustria, Antonello Montante,
who was placed under house arrest on May 14 on charges of
conspiracy to commit corruption.
He is also working on cover-ups and "deviations" in probes
into the 1992 Mafia bomb slaying of anti-Mafia magistrate Paolo
Borsellino, as well as continued investigations into the other
Mob bomb slaying that year, of Borsellino's friend and colleague
Giovanni Falcone.
Tuesday's is the third such threat in Sicily this month.
On October 9 Claudio Fava, chair of Sicily's regional
anti-mafia commission, received an envelope containing a
7.65-calibre bullet.
His commission is also probing the Montante system and the
Borsellino cover-ups.
