THREE members of Khabib Nurmagomedov's team were arrested and taken to jail following chaotic scenes at the end of his win over Conor McGregor.
The 30-year-old was sensational as he destroyed his Irish rival with a fourth-round rear naked choke submission finish.
But it was what happened after the bout that will make the headlines, with McGregor being sucker-punched following the end of the bout.
Khabib made him tap out, before jumping out of the Octagon and brawling with people in the crowd.
Meanwhile, one of his pals leapt over the fence and threw a hook at the fallen Irish star.
Three of Khabib's pals were nicked by Las Vegas cops at the T-Mobile Arena and taken to jail.
UFC boss Dana White said: "A lot of bad stuff, that should not have happened. All hell broke lose. I'm disgusted.
"Three of his guys have been arrested and taken to jail.
"They made it clear the rivalry would not be over after the fight.
Disconsolate Dana White says it's been a bad night for MMA after Khabib Nurmagomedov jumped into the crowd after beating Conor McGregor at UFC229 "I did not see that coming. We had so much security. God knows what is going to happen to Khabib.
"There is going to be a lot of repercussions."
It is understood the trio were later released by police, pending further investigations.
