Bruno Contrada (born September 2, 1931 in Naples, Italy) is the former police chief of Palermo and deputy director of the civil intelligence service SISDE who was arrested based on revelations of former Sicilian Mafiosi turned pentiti, Gaspare Mutolo and Giuseppe Marchese.
In 1992, together with Italian Police head Arturo Parisi, he had a secret meeting with antimafia judge Paolo Borsellino under the direction of the then Minister of Interiors, Nicola Mancino.
He was accused of having informed the Mafia of upcoming police operations, and preventing an early capture of the Corleonesi boss and fugitive Totò Riina.
[6] Falcone had also suspected Contrada of informing the Mafia of his intention to invite visiting Swiss prosecutors to his summer house in Addaura on the afternoon of June 19, 1989, when an attempt was made on his life.
[9] In 2015, the European Court of Human Rights ruled that Contrada was convicted for acts that at that time were not a crime, in violation of the principle of non-retroactivity of criminal law (nulla poena sine lege).
