There will be no prosecution in the case of a man who died just hours after he attended the Swedish House Mafia concert in the Phoenix Park in Dublin last year.
Shane Brophy from Crettyard, Co Laois, died at his friend's house in Lucan on 8 July 2012, hours after the concert.
Mr Brophy was taken to Connolly Hospital Blanchardstown, where attempts were made to resuscitate him.
He died from the toxic effects of a combination of cocaine and ecstasy.
Last February, Inspector John Burke of Blanchardstown Garda Station told Dublin District Coroner's Court the garda inquiry into Mr Brophy's death was at a "pretty advanced stage".
He told coroner Dr Brian Farrell there were still inquiries to be carried out and "people to be interviewed and re-interviewed".
But today Inspector Deirdre Gill told the court there would be "no prosecution" in the case and made an application for a date for an inquest hearing.
Dr Farrell adjourned the inquest until 31 October after members of Mr Brophy's family agreed to attend court on that date.
Mr Brophy was the youngest of eight brothers and sisters.
Last February, Dr Farrell said the toxicology report carried out as part of the post-mortem examination indicated Mr Brophy had used cocaine and an "ecstasy-type drug".
He described the levels in the dead man’s system as being "significant", but told the family that both cocaine and ecstasy could be toxic regardless of the dose taken.
