A vigil has taken place in Dundalk this evening to mark the anniversary of when Kyran Durnin was reported missing.
Gardai are continuing to work on the assumption that the boy, who would now be nine-years-old, is missing presumed dead and that he may have died up to three years ago.
Gardaí said that they have taken more than 570 separate investigative actions in relation to Kyran's disappearance.
The last known images of him were taken in June 2022 when he was six-years-old.
Two people have been arrested, three properties have been searched, and almost 30,000 hours of CCTV footage have been seized.
One of those arrested was a woman in her 20s, who is understood to have been known to Kyran.

A 36-year-old man was also arrested as gardaí carried out an "intrusive" search at a property and its adjoining gardens in a housing estate in Drogheda.
Both the man and woman were subsequently released without charge.
However, gardaí confirmed that the man, named locally as Anthony Maguire, was found dead at his home in Drogheda just days after his release.

Brittany Helen, who organised the vigil this evening said it was to remind people that Kyran's case is still at the forefront of people's minds.
She said: "Although a lot of people want to push his case under the rug, we cannot allow the disappearance of a child go unsolved, not in today's world."
A minutes silence was held at the Square in Dundalk as part of the vigil.
