The death of a 20-year-old man at the Electric Picnic music festival in Co Laois is being investigated by gardaí.
Emergency services were called to assist the man after he collapsed at around 1am.
He was later pronounced dead at Portlaoise General Hospital.
An investigation is under way but gardaí do not suspect foul play.
A post mortem examination will take place on the body later today.
Organisers say their thoughts and sympathies are with the family and friends of the man.
Around 35,000 people are expected to attend at the sell-out music festival over the weekend.
