There is no doubt that violence related to sport activities is a phenomenon that is not possible to avoid even in a modern society. We can speak only about different forms and therefore different intensity of this phenomenon. In Serbia, the issue of violence culminated in the last two decades, when the number of incidents increased, including cases with fatalities, large-scale disturbance of public order and other outbursts of violence both at the stadiums and elsewhere. They resulted in a variety of injuries, damage and property destruction. Political events in which supporters of different sport clubs took part alongide members of rightist organizations, as a rule turned into outbursts of violence, causing damage and destruction. It appears that urban environments have become a center from which this phenomenon is 'broadcast' to the wider environment. Extremist football fans have been registered in all larger towns and cities throughout Serbia. They continually provoke incidents with serious consequences, both at the stadiums and outside them. The cities with the highest rate of violence include Belgrade and Novi Sad. More than a half of all safety issues before, during and after sport events are related to the area of Belgrade, although only 15 % of all sport manifestations are held in this area.
