Police who want to expel the troublemakers to Plaza Urquinaona receive firecrackers and smoke bombs. Police vans raced down the street through barricades and then disperse people. Some people stayed to fight, further protesters ran away down the side streets. A climate of confusion was created because the tension then moved to the streets of the Eixample on which traffic was circulating. Confrontations with police that occurred between October and December 2019 produced multiple arrests and hundreds injured. (October 18,2019. Barcelona, Spain)
