A 22-year-old man accused of stabbing another man at a concert in the Phoenix Park at the weekend has been refused bail at Dublin District Court.
Raymond Donnan from Greenfort Crescent in Clondalkin, Dublin, is charged with five offences including assault causing harm, possession of a knife, violent disorder and two public order offences.
More than 30 other people were also arrested and bailed following Saturday night's concert.
They were charged with assault, drugs and public order offences and are due to appear in court in the coming weeks.
A total of nine people were stabbed in separate incidents - one man was critically injured.
The charges against Mr Donnan are in connection with one of the attacks.
Sergeant Shane McCartan from Finglas Garda Station told the court that he and an off-duty garda had Mr Donnan under observation for some time before arresting him in the Phoenix Park at 9.55pm on Saturday night.
When Mr Donnan was charged yesterday evening he made no reply.
Sergeant McCartan objected to bail because of the nature and seriousness of the charges.
The court heard the alleged victim was attacked in front of his girlfriend, stabbed five times, wounded in the liver and had to get stitches in his elbow and head.
Defence Counsel pointed out that Mr Donnan was unemployed, living at home and receiving €100. His family collected €1,500 as an independent surety, but Judge Gráinne Malone refused bail.
A man who became ill at the concert and later died in hospital has been identified. He was in his early 20s and from Clonsilla in Dublin.
A post mortem examination to determine the cause of his death will be carried out today.
Shatter says MCD needs to clarify issues
Minister for Justice Alan Shatter said concert promoters MCD have issues they need to clarify following incidents at Saturday's concert.
Mr Shatter described what happened as "very unusual" and "unacceptable".
He revealed that the Garda Commissioner will be meeting the promoters.
Gardaí had provided the type of policing at the event that has been provided at other concerts where no events of this nature took place, he said.
''Unfortunately there are always some incidents of young people drinking excessively at these events but we've never had a series of stabbings of the nature that occurred.
''And there are concerns about other matters surrounding this event. I know this is something the Garda Commissioner is taking up with the promoters and I'm awaiting his report following that meeting."
In a statement, the Swedish House Mafia said: "We played a festival in Ireland at the weekend and reports of incidents are coming to us.
''We didn't see anything but have asked for all the info and are respectful of the promoter's need to wait and give us all the clear facts.
''When we know more we will liaise with the festival promoter directly on what we can do to help but for now we have to respect their request to us that we remain quiet and respectful of their event safety processes.
''The festival itself was amazing and we had no idea this had happened and neither did the other numerous artists who played.
''Once we know all the facts we will deal with it in the best way we can. Thank you.''
