Chaos erupted after Conor McGregor's fourth round tap out to Khabib Nurmagomedov on his UFC return.

The Russian retained his UFC lightweight title with a submission victory over The Notorious but three members of his support team were then arrested after an all-in brawl broke out.

They were then released as the Irishman refused to press charges

Fights broke out in and around the cage, with a red-shirted fan landing several blows on McGregor before security intervened. Both fighters were escorted from the arena by police and security.

UFC boss Dana White later told Fox Sports that three members of Nurmagomedov's team were arrested and he refused to hand the Russian the belt.
