THE DUP councillor sanctioned for "misogynistic" remarks about Michelle O'Neill is being probed by the local government watchdog on a separate matter.
John Carson, who earlier this week was handed a three-month suspension for posting offensive comments on Facebook about the Sinn Féin deputy leader, is being investigated after a Ballymena man who was the victim of an arson attack accused him of saying "you have brought this upon yourself".
Raymond Ferguson lodged a complaint with the Local Government Commissioner for Standards following an exchange of messages with Mr Carson in the wake of attacks on his home in the Riverdale area of the Co Antrim town.
Over the summer, Mr Ferguson's property was targeted several times, during which his car was torched, windows in his house smashed, and graffiti sprayed on walls.
Following an arson attack in August, Mr Carson posted a message on Facebook condemning the incident "without reservation" and urged anyone with information to contact the PSNI.
But Mr Ferguson claimed that when he replied to the Ballymena councillor identifying himself as the victim, Mr Carson sent him a "nasty" private message.
He alleges Mr Carson wrote that "by your behaviour you have brought this upon yourself by the low actions you have done".
"I in no way condone what has happened, I condemn it completely, but l will not allow you to play the innocent victim either," the councillor is claimed to have said.
Mr Ferguson told Belfast Live that he felt "sick with anxiety".
The 52-year-old said: "Having a councillor, somebody you would go to for help, for him to do that I was really shocked by it.
"For him to say that I deserved it, that he wasn't going to let me be a victim, what did he mean by that?
"It really affected me. Talk about kicking somebody when they are down."
He said the attacks on his home started after he made a complaint to the Housing Executive and gave a statement to police about an unrelated matter.
He also said he has been the subject of malicious rumours falsely accusing him of being a sex offender.
Mr Carson has not responded to requests for a comment but after the matter was brought to the attention of DUP headquarters, Mr Ferguson received an email from the party's chief executive Timothy Johnston.
In the email, Mr Johnston said he would bring the matter "to the attention of our party officers".
"Clearly from your email you indicate that you have not experienced the sort of help and service expected from a public representative," he said.
The DUP said it would not provide a "running commentary" on its disciplinary and complaints procedures.
