A fight between two stag parties in Carrick-on-Shannon in the early hours of last Sunday morning left a man with a double fracture of his jaw.
The injured party sustained a double fracture of his jaw in the incident and had to undergo emergency surgery in Altnagelvin Hospital in Derry as a result.
Supt Kevin English told the Leitrim Observer that a fight broke out between the two groups of visitors at a B&B in the town.
Both groups were from Northern Ireland, one from Co Derry and the other from Co Tyrone.
He said one of the groups was staying at the B&B and the other group arrived and thought it was staying at the same accommodation and a fight broke out between the parties.
A man was arrested at the scene by gardai and he appeared before Judge Kevin Kilrane at a special sitting of Carrick-on-Shannon District Court on Monday.
Mark Gillespie, 16 Delaney Court, Strabane, Co Tyrone was charged with a Section 3 assault.
He was granted bail on a substantial cash lodgement to return before Carrick-on-Shannon District Court on Tuesday, May 21.
