Thanks to the testimonies and images from the video surveillance systems of pubs and shops, the circle is closing in on the other young people who were with Salvatore Calvaruso, the 19-year-old from Zen accused of the Monreale massacre for having shot, on Saturday night, killing Salvatore Turdo, Massimo Pirozzo and Andrea Miceli and wounding two other people, including a sixteen-year-old.

Another young man was arrested last night :   Carabinieri of the Provincial Command of Palermo have executed an arrest warrant issued by the Prosecutor's Office against an 18-year-old from Palermo, accused - in competition - of the crime of massacre. Samuel Acquisto, in competition with other people still unidentified, allegedly instigated Calvaruso to fire gunshots at chest height in the street where over fifty people were present. Acquisto allegedly assisted Calvaruso during the phases of the shooting "committing acts such as to endanger public safety", the arrest warrant states.

The violence started from a fight related to the speed of a motorbike that was passing between people at a high speed. According to the investigators' reconstruction, Acquisto was the one driving the motorbike that night
