Speaking on his LBC show, Mr Ferrari said it was “extraordinary” the Brussels bloc watched by as hundreds of Catalans were beaten and shot at with rubber bullets.
A panicked Brussels warned Catalonia on Thursday that it risks “abandoning the European Union” by splitting from Spain.
Mr Ferrari said: “It is quite extraordinary that the European Union, and more importantly the European Commission, which is there to represent the interests and health and well-being of European citizens, the European Commission has watched as more than 800 Catalans were beaten.
“They had rubber bullets fired at them, one man was blinded in one eye, another man had a heart attack, fortunately lived, one elderly woman was dragged out of a polling booth by her hair.
“The European Commission, not only has it failed to say anything about the treatment, it’s actually talked about how illegal the referendum was in the first place.

“Why? Because they are absolutely panic-stricken that if Catalonia spins out of Spain, the Basque region will spin out of Spain, Bavaria will spin out of Germany, Silesia will spin out of Poland, you haven’t got an EU anymore.
“It is shameful they take all that money and they’ve not said anything about European Union citizens being clubbed, literally clubbed by police officers.”
The EU is scrambling to avoid a Catalexit, which would see the bloc disintegrate further after an already-chaotic 18 months.
More than two million Catalan voters braved police brutality, which left 800 injured, to choose independence for Catalonia in Sunday’s disputed referendum, according to Catalan authorities.
But the EU, as well as Spain’s central government, has condemned the vote as illegal and unconstitutional and are refusing to acknowledge the result.
In a last-ditch attempt to bring Catalonia back under control EU officials have warned quitting Spain would also mean quitting the bloc.
