It began as a peaceful protest against bull-fighting in the Peruvian capital, Lima. It turned into a fight between police and protesters outside the city's main bullring. Police unleashed tear gas and water cannon against the hundreds of activists who marched on the venue to protest on the opening day of the season. The demonstrators accused the police of heavy-handedness. "We went to the bullring with a banner that said 'Compassion and justice for Bulls' and they grabbed us and beat us."
