Three people were left shaken after being burgled by a masked gang armed with a pitchfork and metal pole on Tuesday in what's been described as a horrific ordeal by police.
The incident occurred close to the Donegal border near Aghyaran.
Two men, one in his sixties and another in his seventies, and one woman, were held under duress during the burglary.
The aggravated burglary occurred in Corgary Road area of Castlederg.
Detective Sergeant Jack said: "It was reported to us around 10.50 p.m. that three masked men entered the property earlier that evening, around 9:45pm, armed with a pitchfork and metal poles.
"There were three occupants in the house at the time - two men aged in their 60s and 70s - and a woman, also aged in her 60s.
"Both men were forced to lie down on the floor on their stomachs as one of the suspects stood over them with a metal pole.
"However, they managed to take the pole off the suspect who then fled along with the other two suspects. A sum of money and three mobile phones were reported stolen."
One of the victims was treated for injuries after what police said was a "horrific ordeal".
DS Jack said: "One of the male occupants sustained minor injuries to his leg and face and was treated at the scene.
“Two suspects are described as being of skinny build and one described of being of a heavy build.
“This must have been an horrific ordeal for the victims. This happened late last night in their home; somewhere they deserve to feel safe and they have understandably been left shaken.
