Gardaí are treating as suspicious the death of a woman in her 50s whose body was discovered near the village of Lixnaw in Co Kerry today.
She has been named locally as Susan Dunne, who was originally from England, but had moved to Lixnaw about two years ago.
A 19-year-old man has been arrested.
The woman's body was discovered shortly after 10am by a neighbour.
It was found at a home at Ballinagearagh, 1km from Lixnaw.
The woman moved to the isolated cottage with her son around two years ago.
Both were seen regularly in the village, but they were known to be private people and kept to themselves.
It is understood there were injuries on the woman's body.
Gardaí preserved the scene once they arrived and a technical examination of the house was carried out.
The man is being questioned at Listowel Garda Station.
The woman's body remains at the scene.
Gardaí are appealing for anyone who may have seen unusual activity in the area to contact Listowel Garda Station on 068-50820.
