Porto Alegre Brazil. 25 February 2011. At least forty people were injured when a mad driver slammed his car into a pack of more than 100 cyclists in the city of Porto Alegre in Brazil. The cyclists, mainly young people, were staging a peaceful demonstration calling for a reduction in the number of cars on the streets. The 47-year-old male driver fled the scene of the incident Friday evening and was later arrested after authorities found his abandoned car over the weekend.
