Police carry a protester away, after demonstrators blocked a street in Frankfurt, central Germany, Friday May 18, 2012. Police in Germany have temporarily detained some 400 demonstrators during largely peaceful protests by Occupy activists. Fankfurt police said up to 1,000 people turned out at some of the unauthorized protest rallies scattered across the city Friday. They say protesters erected barricades, staged sit-ins and tore down traffic signs. The protest group calling itself Blockupy seeks to stage protests over the weekend and has called for barring access to the European Central Bank which sits in the downtown business district of continental Europe's biggest financial hub.
