Conor McGregor is expected to be charged with assault after allegedly punching a man in a Dublin pub.
Video footage of the incident, which is alleged to have happened in April, was published online by TMZ yesterday.
The video shows a man sitting at the bar refusing a drink from the MMA star, who then appears to punch the man in the head.
He is then quickly ushered away by two of the men he was with.
Gardaí have confirmed that investigations are ongoing, and it's understood a file has been sent to the DPP, but no arrests have been made.
