A suspicious object found in a bar in Londonderry on Friday was a viable pipe bomb, police have said.
The alarm was raised after the object was found upstairs in a bar at Stanley's Walk, in the Brandywell area.
The army was called and the alert has ended. In a separate alert, five homes in Derry were evacuated over night.
A suspicious device, left at the roadside at O'Connor Court in Ballymagroarty, turned out to be a hoax.
Two controlled explosions were carried out during the Ballymagroarty alert shortly after 0500 BST on Friday.
Residents have been allowed to return to their homes.
