Police in the North are investigating two security alerts close to the Monaghan-Armagh border in recent days.
A Spokesperson says Police received reports of a 'bang' in the Castleblayney road area of Keady last Friday.
A beer keg was found after checks were carried out in the area.
What's described as a 'crude homemade explosive' was found inside a second beer keg found in the area yesterday.
However, Police say it is not thought to have been viable after it was examined.
Anyone with information is asked to contact the PSNI.
