According to El Pais newspaper, at least 13 people were injured, including three police officers. One person was detained.
These were the first clashes between the police and protesters in Madrid after the verdict announcement.
Since the beginning of the week, Catalonia has been marred in public unrest. Mass demonstrations have been brought about by the ruling of the Spanish Supreme Court to sentence nine Catalan politicians, involved in organizing the 2017 independence referendum, to 9-13 years in prison on sedition charges and the other three to fines over disobedience.
On Friday, what started as a general strike in Barcelona soon grew into public unrest and violent riots. Protesters were blocking roads by barricades, setting these barricades on fire, ripping off the street signs, breaking the windows of nearby stores and eventually clashed with law enforcement near the National Police building. They threw bricks, bottles, crackers and other objects onto the police and burned carton boxes. Police had to fire rubber bullets and tear gas to constrain them, as well as use water cannons to fight the fire.
