THREE MALES DIED of overdoses in Dublin last night with one of them collapsing prior to the Swedish House Mafia concert in the Phoenix Park.

The three males, believed to be in their teens or early 20s, died after being brought to Connolly Hospital in Blanchardstown last night.

One of the men in his early 20s became ill and sought medical assistance inside the concert arena at around 7pm yesterday evening, Gardaí have confirmed.

He was subsequently taken to Connolly Hospital where he was pronounced dead. As yet, the man has not been identified and Gardaí have asked that family and friends check that their loved ones have arrived home safely.

They have asked that anyone who has concerns regarding a friend or relative to contact Blanchardstown Garda Station on 01 666 7000.

The two other males died later in the night from overdoses but it is not known whether or not they had attended the concert in the Phoenix Park.

Gardaí confirmed earlier that seven people were stabbed during the course of last night’s concert. One man has been arrested as part of an investigation into the stabbings.
