In 1980, Fiore and Morsello escaped to London as fugitives after arrest warrants aimed at shedding light on the facts of the massacre at the Bologna railway station. The two were considered unrelated to the massacre, although they belonged, according to the judiciary, to the Nuclei Armati Rivoluzionari. They both stayed in England during the first government led by Margaret Thatcher with the status of political refugees for 20 years.
