Gardaí are appealing for witnesses after a man in his 40s was injured during a brawl after the Dublin Derby yesterday.
The incident occurred on the Phibsboro Road near Dalymount Park after Bohemians hosted rival league side Shamrock Rovers.
The Garda Public Order Unit was called out to Phibsboro when a mass brawl broke out.
A video posted from the scene shows around two dozen people involved in a melée in which punches were thrown.
A man in his forties suffered head injuries and was taken to the Mater Hospital.
A Bohemians spokesman's condemned what happened, saying "anyone engaged in any such behaviour in no way represents the club and its values".
Gardaí say they have collected CCTV footage and are pursuing a definite line of inquiry.
No arrests have been made.
Anyone with information is asked to contact Mountjoy Garda Station
