It may be flights to Charleroi are getting too cheap

Eastern European Gangs Fly to Belgium to Rob Shops

In a secret report by the National Detective Information Service (DNRI) of the Dutch police, it is noted that Polish gangs are regularly flown into Charleroi Airport in Belgium.

There they are given instructions, by SMS, navigation apparatus and even signs on shops, on where they should carry out robberies in the Netherlands. The annual theft amounts to about 220 million Euro. One center of these gangs is the Polish town of Wroclaw; others come from elsewhere in Poland and Lithuania. The gangs often consist of 10 or more people.
