On 30 September 1977, a group of
MSI activists ran out of the party offices at Medaglie d'Oro to chase after people who were outside distributing anti-fascist
leaflets. According to a subsequent testimony in 1981 by convicted neofascist terrorist and
pentito Cristiano Fioravanti, he and Alibrandi, who were among the MSI militants, gave chase to twenty-year-old student Walter Rossi and killed him in via Elio Donato, with the same
9mm pistol which they passed among them. In late 1977, Alibrandi, the Fioravanti brothers, Carminati, Anselmi,
Francesca Mambro, Dario Pedretti, Luigi Aronica, and other far-right militants, most of them former MSI members, formed the group
Nuclei Armati Rivoluzionari (
Armed Revolutionary Nuclei). In his testimony as a
pentito, Christiano Fioravanti later reported that NAR were never a "structured, hierarchical" organization "like the
Red Brigades" and that the
acronym was used by a number of neofascist armed militants for their actions. On 28 February 1978, the third anniversary of the death of
Mikis Mantakas, a Greek student and member of
MSI's student front who was killed in a clash with left-wingers, Alibrandi along with other NAR members, including the two Fioravanti brothers, reached Piazza Don Bosco, near the
Cinecittà district, where they ambushed a small group of young communist militants and killed Roberto Scialabba, an electrician worker. On 27 November 1979, Alessandro Alibrandi, along with NAR members Valerio Fioravanti, Giuseppe Dimitri and Domenico Magnetta, robbed at gunpoint the
Chase Manhattan Bank branch in Rome, while Massimo Carminati acted as
getaway driver. By this time, NAR, through the mediation of
Franco Giuseppucci and Danilo Abbruciati, had connected with the crime organization
Banda della Magliana who acted as
money launderer for NAR's robbery loot. The law enforcement authorities were closing in on Alibrandi and his comrades, so he left the country in 1981 and enlisted in the
Maronite militia of the
Kataeb Party, in
Lebanon. There he trained with the Lebanese whose trainers ostensibly included
Tsahal personnel. stated that Alibrandi had at one time been treated for unspecified wounds in the Israeli
military hospital in
Nahariya. Following the arrests of the Fioravanti brothers and others, he returned to Italy in June 1981 The next target was
DIGOS officer Francesco Straullu who was being accused in far-right media of "
torturing" neofascists caught by the police. Straullu and officer Ciriaco Di Roma were driving in their car through the
Acilia frazione, on 21 October 1981, when they were ambushed and assassinated by Alibrandi and other NAR members. ==Death==
