A man is due to appear in court following an altercation at a Co Fermanagh Hotel.
The incident came after protesters disrupted a political conference at the Lough Erne Resort on Sunday afternoon.
A 34-year-old man arrested by police has been charged with affray, attempted grievous bodily harm with intent, criminal damage and possession of an offensive weapon with intent to commit an indictable offence.
He is to appear at Omagh Magistrates’ Court on Tuesday.
As is normal procedure, all charges are reviewed by the Public Prosecution Service.
The PSNI’s Inspector Taylor said: "It was reported that a conference, which was being held in the area, had been disrupted by protestors and an altercation broke out.
"Officers attended and calm was restored a short time later. Two people were treated at the scene for their injuries with a further four taken to hospital with injuries which are not believed to be life threatening at this time."
