After 15 years , official investigation has determined that the attack was carried out by a small neo-fascist group , call '' Nuclei Armati Rivoluzionari '' . Many conspiracy theories regarding this event have been entertained , including a link between this act of terrorism and the loss of Itavia Flight 870
