Gardaí have confirmed they are investigating the death of a man at a house in Bray, Co Wicklow.
The body of a man (24) has been taken to Loughlinstown hospital for a postmortem, according to a Health Service Executive (HSE) spokeswoman.
It has been reported the man died from a cocaine overdose at a house in the Mountain View area of the town and was found in his bed by his father - although a Garda spokesman would not confirm this.
Elsewhere, two men taken to Midland Regional Hospital over the weekend suffering from suspected cocaine overdoses are stable and recovering.
The 17-year-old from Mullingar and man (26) from Longford town are both in intensive care, but their condition improved this morning, according to the HSE.
The teenager collapsed on the streets of Mullingar early on Sunday morning, while the man was found by a member of his family in his apartment in the town on Saturday afternoon. It is believed that he had been at his Christmas work party on Friday night.
The latest admissions to hospital come following the deaths of two Waterford men, John Grey (23), and Kevin Doyle (21), after they ingested cocaine at a party in the city.
Model Katy French, who was buried yesterday, is also suspected to have taken cocaine before her death.
Longford-Westmeath TD and former government minister Mary O'Rourke said she believed that the death of Ms French was not acting as a deterrent, although she stressed that it had not been confirmed that her two constituents, in Midland Regional Hospital, had taken a drugs overdose.
"It should be a deterrent. It's a horrible deterrent to all of us, but I've heard of some young girls who are putting Katy up on to a pedestal. If we are looking at a deterrent, I think that some young people would be inclined to say: 'oh, she had a wonderful life, didn't she?'"
Fine Gael community affairs spokesman Michael Ring has called on senior Ministers and the Garda Commissioner to hold a crisis meeting to tackle the problem of cocaine.
