People such as Oreste Scalzone, Franco Piperno, professor in Calabria University, Toni Negri in Padova or Franco Berardi, aka Bifo, at Radio Alice were the movement's most well-known figures. The movement became particularly active in March 1977, after the police in Bologna killed Francesco Lo Russo, a member of "Lotta Continua". This event gave rise to a series of demonstrations in various parts of Italy. Bologna University and Rome "La Sapienza" University were occupied by students. On orders from Interior Minister Francesco Cossiga the "carabinieri" surrounded Bologna's university area. This repression met with some international protest, in particular from French philosophers Michel Foucault, Jean-Paul Sartre, Gilles Deleuze and Félix Guattari, who also denounced the Italian Communist Party's (PCI) opposition to the University occupation. The PCI was supporting at this time Eurocommunism and the historic compromise with the Christian Democrats.
