An investigation is under way following the discovery of skeletal remains at Ballyandrew, about half-way between Ferns and Kilrush.
The remains were discovered in a ditch by the side of a road by a person out walking at 11.30 am.
The scene has been preserved pending the arrival of a State Pathologist.
Gardaí say they do not yet know how long the remains have been there.
Anyone who can help with enquiries should call Enniscorthy Garda Station (053 9242580) or the Garda Confidential number 1800 666 111.
