The Spanish Government has replied to Catalan deputy Alfred Bosch’s query on the issue that instructions have indeed been given to the Spanish police to seize Catalan independentist flags in sports events, just like it happened in Madrid last May during the Spanish Cup’s Football final in Madrid where it was reported the Spanish police seized Catalan starred flags from Barça supporters.
The Spanish Government says this is done because “displaying them could trigger an adverse reaction and violence from certain supporters” (CA). Even though they confirm that the Catalan Estelada (Starred flag) is not illegal per se.
Also during that match it was reported that at least one young man was beaten up by the Spanish Police for displaying a Catalan independentist flag and later another supporter was fined with 3001 euros for wearing a Catalan independentist scarf (CA).
However, the Spanish police didn’t seem to have a problem with the fascist symbols displayed during the fascist demonstration which took place in Madrid on the same day.
