The violence forced the referee to conclude the match early, with the Chinese lagging 2-1. The game was the second in China's warm-up series in England.

Two Chinese footballers have suffered flesh wound and one injured severely. England local police started to investigate into the riot.

Local police paid high attention on the case and set about investigating the case.

Queens Park Rangers took an easy lead in the first half after the Chinese keeper failed to intercept a long pass, gifting the Rangers with a rare chance to chip a drive into the open net.

China rallied to level the score in the second half with a long shot from Gao Lin, but conceded a second goal to the Queens Park Rangers just minutes later.

Then a fierce quarrel broke out between Gao Lin and one of his rivals after they collided with each other in the 75th minute, transforming the field into a boxing ring. Even the substitutes on the sidelines joined in.

Chinese Olympic team head coach Chinese Ratomir Dujkovic showed his dissatisfaction on the conflict, saying his players need to focus on the game and stay calm whenever unexpected incidents occur on the court. But other coach group members refuse to air their view.

The Chinese team started touring Europe last month as part of the training designed to secure them a place in the top four teams at the Beijing Olympic Games in 2008.

But all their games in England have been marred by brawls. A similar scene occurred when they lost 1-0 to Premiership powerhouse Chelsea on Monday.

China has stepped up its preparation for the Olympics under the helm of Serbian coach Dujkovic, who has announced he wants his team to take a medal at the Beijing Olympics. Dujkovic unexpectedly led African side Ghana to the World Cup in Germany in 2006.

China will play their last match on their tour against English Championship side Brentford on Tuesday.
