A Coleraine brother and sister whose home was ransacked on Wednesday night say the intruders told them they were from the UDA.
The pair aged 70 and 82 were confronted by five masked men who burst through their front door demanding drugs.
Once inside the intruders moved through the rural Camus Lane property ransacking rooms as they went.
Despite their ordeal, the siblings say they will not be forced out of the area.

Detective Sergeant Molloy said: “We received a report around 9:50pm that five masked men had forced their way into a house in the Camus Lane area earlier in the evening, at approximately 9:15pm. The men ransacked the house and searched a male occupant, aged in his 70s.
"The five men left a short time later, taking three torches and milk from the house with them, and drove off in a dark-coloured vehicle, possibly in the direction of Kilrea.
"Neither the male occupant, or the other female occupant in the house, who is aged in her 80s, were injured.
"However, this was a frightening ordeal for both the occupants who have been left badly shaken.
"The suspects are described as wearing black baseball caps, black anoraks, blue-coloured jeans with blue plastic masks covering their faces.
"I want to make a number of appeals today. Were you in the Camus Lane area last night, around 9pm? Did you see any suspicious activity? Or, have you seen any suspicious activity in the area in recent months?
"If you think you have information which you believe could help our investigation, contact detectives in Coleraine on the non emergency number quoting reference number 1372 29/08/18."
