John Boyle of Leck Cottages, Oldtown, Letterkenny appeared at Mullingar District Court this morning.
The 46 year old was charged with four different counts of assault causing harm. He was also charged with the illegal possession of a knife.
The attack happened outside the Voodoo Nightclub on Lower Main Street after 1am in the early hours of Sunday morning.
As a result of the attack, a Garda Sergeant and three nightclub doormen were stabbed and had to receive treatment at Letterkenny General Hospital.
The owners of the nightclub, Jason and Sharon Black, have condemned the attack on their employees and on the Garda Sergeant who was named locally as Aidan Doherty from Buncrana.
The accused was released to appear at Letterkenny District Court on September 15th next.
The court was also told there may be other charges arising out of the incident.
The tree nightclub doormen have since been released from hospital but the Garda Sgt is still receiving treatment.
