Video: Man suffers brutal gang beating in Dublin city centre
A young man was knocked unconscious by a vicious kick to the head as he enjoyed the celebrations following Conor McGregor's historic win.
The incident unfolded outside a city centre pub shortly after the McGregor-Aldo bout concluded.
The young man was attacked by a group of men on O'Connell Street.
The innocent victim was punched several times before being kicked in the face by assailants, leaving him unconscious on the street.
Dozens of shocked onlookers watched as the man was subjected to at least three punches and at least one violent blow to the head before being kicked while on the ground.
The shocking video shows the brute force of the kick which knocked the man out. During the incident one woman was visibly distressed and can be heard screaming at the attackers to stop, while another man described the scenes of violence as "absolutely disgusting".
The group of men responsible for the attack quickly fled the scene as an ambulance was called for the victim.
It is understood that the attack was related to an earlier incident inside a popular city centre venue where the UFC title clash was being screened.
An argument broke out between two men, which turned violent quickly. The man who later kicked the victim outside threw a glass bottle at the victim, narrowly missing his face.
In a bizarre twist, the attacker then picked up a full-size Christmas tree and hurled it at the victim in the packed venue. A short scuffle ensued and the victim was left with a busted lip before security intervened. The attacker was escorted by staff out the side entrance of the venue.
The second assault on the same man took place outside shortly afterwards as UFC fans left the venue.
The injured man regained consciousness after the second attack, but was unable to sit up.
He was placed in the recovery position by witnesses as he awaited medical attention.
The shocking assault took place shortly before 6.30am on Sunday morning.
Dublin Fire Brigade confirmed that a 25-year-old male was brought to the Mater Hospital by one of their ambulances - however, his condition was not known last night.
Gardai said that they have no record of an assault that matched the incident, but it is sometimes the case that statements about a public order incident or an assault are made some time after the fact, sparking an investigation, a spokesman said.
