Human remains found at a house in south Dublin may have been there for a year or more.
Council workers clearing the home on Sallynoggin Road discovered a hand grenade at the property on Wednesday morning. Residents in the area were evacuated during the incident just after 9.30am.
Gardaí and the Army Explosive Ordnance Disposal team attended the scene, removed the device and destroyed it at a nearby location.
Work resumed on the house a number of hours later after the scene had been declared safe. The Irish Times reports it was then the body, believed to be an elderly man, was discovered.
Gardaí in Dun Laoghaire say they are investigating all of the circumstances but it's not being treated as suspicious.
The body was removed from the scene to the Dublin City Mortuary, where a post-mortem took place, the results of which are not being released for operational reasons.
A file is now being prepared for the coroner's court.
