Two of the three people who left a mandatory quarantine hotel Sunday have now returned to the facility.
One person who absconded from the Crowne Plaza near Dublin Airport is back in their room after being located by Gardaí
In a separate incident, two more residents left the hotel - one has since returned and a search is ongoing for the other person.
The first people were brought to the facility from Dublin Airport less than two days ago after the new rules came into force on Friday.
It is understood Gardaí were called in by the Defence Forces liaison officer at the hotel near the airport yesterday afternoon.
The Department of Health said anyone who breaks quarantine faces a fine and jail time.
However, it refused to comment further, saying it would not discuss individual cases "in the interests of protecting confidentiality".
