Bosnian and Serbian spectators attacked each other with lawn chairs after the third-round Australian Open match between Serbian Novak Djokovic and Bosnian-born Amer Delic. Police arrested two men and kicked 30 people off the grounds for fighting.

Apparently, these type of outbreaks have been commonplace at the Australian Open since 2007 and police even added to security measures this year in an unsuccessful attempt to keep the violence to a minimum.

The poor woman who took the chair to the face probably wishes they did more.
