Police have said that a bomb found at a County Tyrone golf course had the capability to kill or cause serious injury.
Bomb disposal experts made the device safe after it was discovered at Strabane Golf Club on Monday morning.
The operation followed information received by police that a device had been left in the Ballycolman Road area.
Strabane area commander, Chief Insp Andy Lemon, said it was potentially deadly.
"This device comprised nuts and bolts packed with explosives into a pipe.
"While police may have been the intended target, golfers, ground staff or members of the community passing by could have been killed or maimed," he said.
He added: "This bears the hallmarks of an attempt to draw police into the area. But this was an attack on the community as much as on the police.
"I believe that the vast majority of people in Strabane do not want this type of incident and I would call on them to give us their assistance in bringing those behind it to justice."
Ballycolman Avenue, which was closed this morning during the alert, has now reopened.
