The body of missing woman Marian Power has been found.
The Garda Water Unit discovered her body shortly after lunchtime.
The body has been taken to Blanchardstown hospital.
Ms Power walked out of a hospital at the beginning of the week and hasn't been seen since.
Ms Power was "a very low risk" patient at the open psychiatric ward of the hospital.
She was receiving treatment there of her own accord and was also free to leave of her own accord.
The mother has been described as bubbly and friendly.
CCTV footage of Ms Power walking away from the hospital at around 9am on January 13 was the last official sighting of her.
