At least thirty Bosnian and Serb tennis fans were ejected from the Australian Open following a race riot on Friday.
According to The Daily Telegraph, two groups of fans were involved in what police called a "chair throwing competition" in Garden Square at Melbourne Park around 4 p.m. this afternoon.
Two people were charged with riotous behaviour and a third was given an on-the-spot fine.
A chair hit one woman during the confrontation, and she sustained minor injuries. Police say she was not connected to either group and does not want to take the matter further.
Police were later forced to intervene again when the fans continued their confrontation outside the venue.
Inspector Chris Duthie, speaking at a press conference moments ago, said the majority of the fans were not wearing national colours, making it difficult for police to anticipate the incident.
The scuffle broke out following a match between Serbian tennis player Novak Djokovic and Bosnian born Amer Delic, who now lives in America.
Defending champion Djokovic won the match 6-2 4-6 6-3 7-6 (7-4).
Before today's match, Delic wrote on his personal blog to appeal for calm from his fans ahead the Djokovic clash in light of their countries' troubled history.
"As we all know, Bosnians and Serbs have had some differences in the past. However, this is not the place nor time to settle those differences," he wrote in his blog.
Police removed some fans from the arena during Delic's Wednesday match against France's Paul-Henri Mathieu, who compared the noise and heckling to a football game.
