It all went down on the casino floor at the Aria Hotel in Las Vegas early Saturday morning. Suge can be seen throwing haymaker after haymaker … but it doesn’t look like he landed a single punch.

According to an eyewitness … Suge flew off the handle when the little man approached him with a challenge … saying, “I can take you.”

Eventually, the whole thing was broken up — and cops were spotted at the hotel soon after. We’re told Suge was not arrested over the incident.
