Kerrie Byrne (3) Mary Ellen Byrne (8) and their aunt Barbara Doyle (20) died in a house fire at Church Lane, Kilcock, Co Kildare on September 20th, 1987.
On Tuesday, a man in his 50s, who had never come to the attention of gardaí before, was arrested in connection with the deaths.
A file is now being prepared for the Director of Public Prosecutions (DPP).
Last week, on the anniversary of the fire, gardaí announced they had upgraded the inquiry into the three deaths to homicides after a cold case review.
The suspect was arrested in north Co Dublin before on Tuesday afternoon and was taken to Leixlip Garda station from where the investigation is being run.
