Gardaí have confirmed that a new file has been sent to the Director of Public Prosecutions in respect of the Stardust fire that killed 48 people in 1981.

It follows a complaint made by researcher Geraldine Foy concerning evidence that five of the young people were already dead before the alarm was raised about a fire in the seating area.

Ms Foy, who has worked with families of the victims for over ten years, said there is evidence that five young men had died from fumes before the seat fire, and up to 12 metres away from that location.

Another file was sent to the DPP last August, based on evidence that a 999 call was made from outside the Stardust by a resident who saw a fire on the roof.

This was said to be at the same time a 999 call was made from inside the dancehall about the seat fire, which the original tribunal held was the origin of the blaze.

The families believe the fire started in a storeroom and have disputed the layout of the building given to the original tribunal.

The file sent last August alleged perjury at the tribunal but the DPP declined to take any action.

A Garda spokesperson said they could not comment on the new file.

A previous review of new evidence removed the tribunal finding that the cause was "probably arson" in the West Alcove seating area but said there was insufficient evidence to establish the origin of the fire.
