Park concert marred by violence
A concert was marred by tragedy when one reveller died, nine men were stabbed and two others assaulted.
Detectives have not yet identified the victim, who is believed to have died from a suspected drugs overdose at the Swedish House Mafia in the Phoenix Park in Dublin.
Elsewhere three of the men injured in a knife attack remain in a serious condition in hospital. A 23-year-old suspect was arrested over a number, but not all, of the stabbings at the open-air gig.
Denis Desmond, managing director of MCD Productions which promoted the gig, said every possible precaution had been taken to ensure the safety and security of the crowd.
"Despite our best efforts - with security and gardai personnel levels well in excess of the required numbers for a licensed event of this size - there is only so much one can do to combat anti-social behaviour," he said.
Some 45,000 fans filled the venue for the gig, which featured Snoop Dog, Tinie Tempah, Calvin Harris and headlined with the electronic dance music group, Swedish House Mafia.
A Garda spokesman said a man in his 20s became ill and looked for medical attention from staff at about 7pm on Saturday. He was taken to Connolly Hospital Blanchardstown where he was later pronounced dead.
"Gardai have not been able to identify this man and are asking family and friends to check that loved ones have arrived home safely from the event," a Garda added.
A total of 11 people were assaulted during the night, including nine stabbings. All were aged in their late teens or 20s, and were stabbed between 8.30pm and 1am. Several were attacked by the same person.
"A number of the victims required treatment at Connolly Hospital Blanchardstown and three people continue to be treated at the hospital," he continued. It is understood one of the men in his mid-20s was stabbed several times in the back. About 30 people were arrested during the evening for minor public order and drugs offences.
