Antonio Imerti (Villa San Giovanni, August 22, 1946), also known as "Nanu feroce" ("fierce dwarf"), is an Italian criminal and a member of the 'Ndrangheta, the Calabrian mafia. He was born in Villa San Giovanni and controlled the Fiumara di Muro neighbourhood in Reggio Calabria.
He was one of the protagonists in the Second 'Ndrangheta war which raged from 1985-1991 between the Condello-Imerti clan and the De Stefano-Tegano clan, which left 621 deaths. His marriage in 1983 with Giuseppina Condello – the sister of the Condello brothers, underbosses of Paolo De Stefano – triggered the conflict. The De Stefano clan feared the new alliance might challenge their power base. The conflict exploded in 1985, two years after the marriage and saw practically all the 'ndrine in the city of Reggio Calabria grouped into either one of two opposing factions.
The war started with a failed bomb attack on Antonio Imerti on October 11, 1985, which left three of his bodyguards dead. Two days later, his rival Paolo De Stefano was killed and suspicion fell on Imerti as the one who ordered the killing.
Imerti escaped a second bomb attack on July 7, 1986, and subsequently became a fugitive. He was arrested on March 23, 1993, in Reggio Calabria, together with his brother-in-law Pasquale Condello. Newspaper reports mentioned that Condello might have surpassed his former boss – and there had been speculation that Condello might have killed Imerti when they both were still fugitives. However, although the speculation proved to be false, Imerti’s power had declined because of his opposition to a 'pax mafiosa' to end the war between the opposing clans in Reggio Calabria.
