Gardaí have confirmed investigations in relation to the incident are ongoing.
However, no arrests have been made.
The head of UFC has confirmed the man in the video is Conor McGregor.
Dana White said "the only reason we're talking about this is because it's Conor".
The UFC President "when you're a high profile guy and a professional guy, you can't do it".
Dana White also claimed "a lot" of "guys get punched in the face in a pub in Ireland every day".
