Skrillex and Diplo Gang Stabbings at Big Vegas Show

A violent fight was swept under the rug in Vegas over Labor Day, when 4 people were seriously stabbed at a Skrillex/Diplo show.

It happened at XS Nightclub inside the Encore hotel. Law enforcement tells TMZ, a huge fight involving around 20 people broke out in the middle of the show, leaving 4 with stab wounds. Our sources say it has all the markings of a gang fight.

We’re told the injuries were serious including a punctured lung and spleen but everyone survived — one victim admitted to gang ties and didn’t want to go forward with any charges.

However, law enforcement tells us they have arrested someone on 3 counts of attempted murder. That said, cops are having problems developing the case, because almost everyone they’ve tried to interview developed a case of amnesia.
