It has emerged that six people were brought to hospital from the Twisted Pepper music venue on Middle Abbey Street, Dublin the night Ana Hick collapsed.
The 18-year-old from Dalkey was brought to the Mater hospital on Saturday night but despite efforts to save her she remained seriously ill and was pronounced dead at the hospital on Sunday afternoon.
Gardaí investigating Ms Hick’s suspected drugs death believe they have identified a man who had been selling drugs to the teenager and some of those in her social circle.
A number of young women known to Ms Hick have been spoken to by the investigation team. Detectives from Store Street station, where the inquiry is based, are said to be very satisfied with the level of information supplied.
They believe a man known to Ms Hick and her friends had been supplying drugs to some of them since last year and that Ms Hick had taken a form of ecstasy tablet just before she died.
While the results of toxicology tests are required before the exact cause of her death can be established, the case is being treated by gardaí as a drugs death.
Ms Hick, who would have turned 19 on Tuesday, collapsed on Middle Abbey Street in the early hours of Saturday and died in the Mater hospital on Sunday evening.
The teenager had been out with friends at the Twisted Pepper nightclub before she became unwell. An ambulance was called and took her to the Mater.
Ms Hick was nearing the end of a six-month course on acting for camera at the Irish Film Academy in Temple Bar at the time of her death.
She had graduated from Loreto College in Dalkey last year and was hoping to develop a career as an actor.
