"I offered to take it back if he didn't want it," he said.
"Next thing I knew he rushed towards me, pushing me against the wall and wrapping his hand around my throat, digging his fingers right in.
"I managed to break free and back off away from the property, at which point he shouted at me, threatening to kill me."
He added: "I haven't had such a shocking experience in my 14 years in local politics."
