From VilaWeb via Zero Hedge (Google translation):
This afternoon (09.23.2015) held an unusual movement in the branch of the Bank of Spain, Barcelona, Catalonia Square. Over thirty armored vans were entering and leaving the building shortly after an unknown direction. Many people have the photographs. The Bank of Spain has refused to comment on the operation or indicate that it was but people working in the area have said that is not a normal deployment.
