YouTube has deleted footage showing two teenage girls fighting in a vicious brawl in Cork last Friday.
According to the Irish Examiner one girl had teeth knocked out in the pre-arranged fight in Ballyvolane.
The girls' names and the time of the fight was posted on Twitter hours beforehand and a crowd of around 200 teenagers turned up to watch.
The disturbing footage which has now been removed showed the crowd chanting as the girls grabbed each other by the hair, kicked and punched each other.
