The splinter Loyalist Volunteer Force was today being blamed for a bomb attack on a Catholic family's home in Lurgan, Co Armagh.
A mother and daughter escaped injury when a blast-type device exploded at the front door of their house in the town.
British army experts defused a second bomb found in the garden of the property at Demense Avenue, where the family has lived for 25 years.
Graffiti was also daubed on the garage door before the attackers made off, a security source said.
"It's an LVF-run town. This kind of attack is right up their street. They pick on an easy target," he added.
But a source close to the group denied it was involved: "It is a lot of nonsense. There was no reason or logic to it."
Earlier, the Ulster Defence Association denied that it had carried out the attack.
