Gardai excavating a garden amid claims two new born babies were buried there have found no human remains.
Searches have been on going around a property in Dublin since April.
The probe was triggered after a woman came forward to claim she had been sexually abused in the 1970s and two babies she had given birth to had been killed and buried.
A Garda spokeswoman said the search had now concluded.
“No evidence was found,” she said.
She said a file would be prepared for the Director of Public Prosecutions.
