14 September 2002,
The Ertzaintza used water tanks against 30,000 people demonstrating under the motto ‘Gora Euskal Herria!’ from the Abertzale left. Fill Autonomy Street, the Ertzaintza stopped the head of the demonstration in Plaza Zabalburu with three rows of police, twenty vans and a water tank.
Two weeks earlier, he illegalized Batasuna and banned the demonstration. The Ertzaintza started throwing balls and the protesters sat down, trying to ease the situation with their arms up. The Ertzainas tank began to pour water against them, first running water, then blue water.
They caused more than twenty injuries, among which pelotazos rose in the eye and chest. The image given by the Basque Government to the head of Ibarretxe has entered the political history of Euskal Herria: protesters holding ikurrina attacked with water tanks.
