Violence broke out at the 6th annual Urban Music Awards (UMA’s) in London tonight resulting in three men being treated for stab wounds. Full story HERE. Eye witnesses reported champagne bottles and chairs being hurled around the venue as the event descended into pandemonium. Estelle, Dizzee Rascal and Leona Lewis were all due to perform. Sway won Best Hip Hop Award, performing F UR X with fellow rapper $tush but not long after the violence broke out. A sad outcome to an event that has always promised to eclipse the often criticised MOBO Awards. Will this be the end of the UMA’s?
