Many construction projects in Bulgaria launched in the days of the property boom have been left unfinished. Some people look at this as an opportunity to destroy these semi-finished buildings in order to collect scrap which they later sell. The most striking case is in Blagoevgrad, not far from the ski resort of Bansko, where a Polish company could not complete the shopping mall which they started building on the site of the largest once dairy in the area. Three years ago the Polish investors paid 6 million Euros for the dairy. Now the only thing left from the unsuccessful construction project is shapeless concrete, as all iron bars have been sold for scrap. There is no sign of the investors and they had not paid their property tax, which hinted Kostadin Paskalev, the former mayor of Blagoevgrad to ask Interpol for help to find them.
