Conor McGregor brutally floored a partygoer with two punches at the infamous Pacha nightclub in Ibiza on Tuesday morning.
The disgraced fighter was seen hitting the reveller on the Spanish party island as he boozed until the early hours.
The 36-year-old was in conversation with a man before putting his arm around his shoulders and lashing out on the dance floor at 5:53am as music continues to loudly blare.
He speaks to the man for a few seconds before hitting him with his left hand while holding a glass of alcohol in his right.
