The alleged victim suffered a suspected broken jaw and damage to his eye.
The attendee alleged he was assaulted by a worker early in Saturday.
A worker at Electric Picnic has been charged with assaulting a festival attendee, with sources saying that the teenage staff member allegedly punched the victim in the face.
The victim suffered a suspected broken jaw and a cut to the eye during the altercation, according to reports from the Irish Mirror. The alleged attack occurred in the early hours of Saturday morning during the second day of the festival in Stradbally.
More than 80,000 punters are attending the festival, and at least 4,000 men and women are working at the event, which began on Friday. Electric Picnic remains the biggest music and arts event in Ireland.
Sources say that the festival has largely passed off without incident, but gardai were contacted by an attendee early on Saturday who alleged he had been assaulted by a male working at the site.
Officers on duty at the site quickly launched an investigation and later arrested a teenage worker. He was charged with assault causing harm and appeared at a special sitting of Tullamore District Court in Co Offaly on Saturday evening.
The maximum penalty for that offence is five years in prison and a fine at the Circuit Court level.
Gardai confirmed on Sunday that a man had been charged following an alleged incident in Stradbally. We understand that the incident took place at the festival itself.
A spokesman told us: “Gardaí arrested an adult male (aged his late teens) in connection with an alleged assault in Stradbally, Co. Laois on Saturday 29th August 2026. The male has since been charged and has appeared before the courts.”
Electric Picnic has been contacted for comment.
