Bonanno was arrested with a Greek anarchist named Christos Stratigopoulos. Their connection was directly stated by the Consipiracy of Fire Nuclei group in a statement claiming a failed bomb attack during a speech by former Greek prime minister Kostas Karamanlis.

The Italian intelligence service has highlighted the connections between Alfredo Bonanno and the Greek insurrectionists in a recent document presented to the parliament.

According to the report, anarchism has gone global and Greece has turned into a strategic base for Italian revolutionaries, where Bonnano is "a leading protagonist of the global anarchist stage".

The Italian intelligence service also recalled that five other Italian anarchists were arrested in Athens in December 2009 during the protests for the death of a Greek militant and warned that the "level of anarchism risk" was growing and must not be underestimated.

On Tuesday a bomb went off at the Swiss embassy in Athens but there were no immediate reports of injuries. It is the latest of a series of bomb attacks which have recently struck the Greek capital's foreign embassies.
