Despite being scheduled to appear at the R&B festival Summerbeatz next month, Akon has now been told he will not be able to perform.

The decision has been made by the organisers of Melbourne's Rod Laver Arena, who are concerned that violence will break out if he does.

The American singer's previous gig last October, ended with two rival gangs brawling in the crowd and Akon jumping in to pacify them.

Promoter Dwayne Cross said: "We have toured Akon in Australia many times before and we are extremely disappointed that Melbourne misses out on seeing such an amazing and popular performer; however, this situation is completely out of our hands."
