An 18-year-old boy has died at Cork University Hospital after falling ill at a house party on Monday night.

He was hospitalised after ingesting the psychoactive substance, N-Bomb, at the party in Cork City.

The boy, who is from Millstreet in Cork, has been in a critical condition since Tuesday but Gardai have confirmed that he passed away at the facility this afternoon.

A number of others were treated in hospital but have since been released. 

A 29 year old man was arrested in connection with the supply of the drug and was later released without charge.

A file is being prepared for the DPP.

N-Bomb is a stimulant with hallucinogenic effects and it is a controlled drug under Irish law.

The World Health Organization has reported a number of deaths from the drug in other countries, including Australian, Britain and the United States.

Through a HSE spokesperson, the boy's family has appealed for privacy.
