Sicilian prosecutor suffers another 'act of intimidation'
Messina official pursuing Mafia head Messina Denaro06 February, 18:48
Marcello Viola's office was broken into two days ago and files may have been stolen, police said Thursday.
Last year a bug was found near his office.
He also received threats along with another prosecutor.
Viola is among those closing in on Messina Denaro, who took over the Sicilian Mob when Bernardo Provenzano was caught in 2006.
