Following Barcelona's 3-1 victory in the Champions League Final on Saturday, supporters of the club took to the streets in the Catalan capital.
Celebrations, though, turned violent as they became protests of Spain's high unemployment and austerity measures.
Park benches and bus stops were razed, 84 were arrested, over 130 were injured — including 37 police officers — and 18 were hospitalized, according to Rapid News.
Police were forced to use rubber bullets to quell the riots.
