The October 1978 Getxo attack was a gun attack by the Basque separatist organisation ETA which occurred on 22 October in the Basque town of Getxo, a suburb of Bilbao. The attack occurred six weeks before a referendum to approve a new Spanish constitution. The targets were a group of four civil guards who were returning from policing a football game involving Arenas Club de Getxo. After the game had finished, the civil guards were returning to their barracks, walking along Maximo Aguirre Street in the town.
