Six people were injured following a 'large altercation' at a luxury five-star resort in Co Fermanagh on Sunday afternoon.
The disturbance is believed to have broken out when a political conference, that was being held at the Lough Erne Resort, was disrupted by protestors around 1pm.
A 34-year-old man was arrested following the brawl on suspicion of criminal damage and possession of an offensive weapon and remains in custody.
