An area in Cootehill, Co Cavan had been sealed off earlier after an explosive device was found.
The army bomb disposal team was called to the scene which is believed to have been a residential area just before midday when a member of the public came across the device.
A cordon was put in place, roads were closed and a number of nearby houses were evacuated.
The device was understood to be found as to be viable and was rendered safe by a controlled explosion. All the evidence from the scene has now been handed over to Gardai.
