"We left the hotel at 19:45 and went down the street. The bus turned into the main street, when there was a huge explosion. I was sitting in the back row next to Marc Bartra, who was hit by fragments of the broken window. After the bang, we all ducked down on the bus and whoever could got on the floor. We didn't know what else was going to happen. The police were quickly on the scene and they handled the situation. We're all shocked. Nobody thought about a football match in those minutes."
