Speaking to Nolan Live, John said he had previously moved station and house after dealing with dissident republicans on “a weekly basis”.
“They started to make [it] known that they knew me, my name, graffiti went up of me… photos of me posted online… comments made.”
He was then advised that there was “an aspiration” for dissident republicans to learn more about him.
He moved after deciding it “wasn’t worth the risk” to his family if he had stayed.
He said he was starting to feel “content and safe at home” when the data breach happened.
