Police tried to disperse the crown of demonstrators who had intruded a celebration of the town at Raspall Square in the Barcelona neighborhood of Gracia.
At least one demonstrator was arrested in clashes between riot police and protesters.
Laura Riera, was convicted of cooperating with the terrorist group, Euskadi Ta Askatasuna (ETA), the protestors however, believe she was innocent.
ETA is an armed Basque nationalist and separatist organization founded in 1959.
