A 46-year-old man will appear before a sitting of Mullingar District Court later this morning charged with stabbing a Garda sergeant and three nightclub bouncers in Letterkenny, Co Donegal.
The sergeant injured in the incident is still receiving treatment at Letterkenny General hospital for his injuries.
The incident took place in the early hours of Sunday morning outside the Voodoo Nightclub in Letterkenny.
It is believed the man was refused entry to the nightclub and began to cause a disturbance. Gardaí were called and the man then produced a knife.
The sergeant was stabbed in the hand. It is not believed injuries to the four stabbed are life threatening.
The incident took place as hundreds of people socialised in the town during the Letterkenny Live Festival. The night had up to then passed without any major incidents.
