The loyalist Ulster Defence Association (UDA) is suspected of targeting former members of its political wing who do not back its anti-Belfast Agreement political stance.
The Co Antrim home of Mr David Adams was targeted in an attack last week, it was confirmed today.
Mr Adams is a former member of the Ulster Democratic Party, which folded two years ago during turmoil within loyalism that led to the UDA withdrawing its backing for the Agreement.
Mr Adams confirmed today that "some security equipment" at his home at Maze outside Lisburn was damaged in the early hours of Thursday morning. Police confirmed they were aware of criminal damage to a house at Maze on October 16th.
Security sources indicated that they believed the UDA was responsible, but Mr Adams would not be drawn on who he thought was behind the attack. "I don't want to exacerbate the situation," he said.
Mr Adams is a member of the Lisburn District Policing Partnership (DPP) - one of the policing bodies set up in Northern Ireland's 26 council areas to give local people an input into local policing.
It is believed to be the membership of the DPP - they were set up as part of the peace agreement - which the UDA is opposed to.
They are also understood to have blocked him from addressing the annual conference on Saturday of the Progressive Unionist Party which speaks for the rival Ulster Volunteer Force.
News has also emerged of threats against a Lisburn drug-awareness scheme in Lisburn that is managed by Mr Gary McMichael, one-time leader of the UDP.
