„In the early 2000s, Icelandic businessmen Thor Bjorgolfsson, Björgólfur Guðmundsson and Magnús Þorsteinsson acquired and created extensive banking and investment companies (with complex offshore arrangements) which were then followed by a financial crisis in Iceland. Simultaneously companies such as Novator Partners acquired billions of euros worth telecoms and other companies around Europe. Investigators have found reasons to believe that the money originated from Russian mafia. In 2005 a group of Danish journalists found that all three have backgrounds in Saint Petersburg, where they ran beverage businesses in the 1990s. The report provided details about their activities in Russia, including links to Vladimir Putin whose office helped the Icelandic businessmen.^[21] Their brewing company was founded by six companies registered in Limassol, Cyprus, a center for Russian money laundering. Björgólfur Thor Björgólfsson was president of all of them.^[21] Their competitors in the Saint Petersburg brewing market faced severe problems. For instance, Ilya Weismann, deputy director of competing beverage company Baltic, was assassinated on January 10, 2000. Later Baltic director general Aslanbek Chochiev was also assassinated. One competing Saint Petersburg brewery burned to the ground.^[22][21] An article in The Guardian (2005) wondered where the Icelandic billions come from and noted that in the 1990s the three businessmen „were not only ploughing money into the country but doing it in the city regarded as the Russian mafia capital. That investment was being made in the drinks sector, seen by the mafia as the industry of choice.“
