People stand in front of a banner reading "Stop police violence for an independent investigation" during a demonstration against police violence and vandalism in the Stockholm suburb of Husby on May 22, 2013. Rioting spread across Stockholm immigrant districts in a third night of unrest, raising fears that decades of integration efforts have gone dangerously awry. The riots are believed to have been sparked by the deadly police shooting last week of an elderly man in Husby -- a run down, low-income suburb that is only a short walk away from the Kista Science Tower skyscraper, a symbol of the booming IT sector in one of Europe's wealthiest cities.
