The incident happened in the Craighill area of the town, with the victim hospitalised for minor injuries after the attack.
Councillor Neil Kelly said: “I am shocked at this callous and brutal attack. Everyone has the right to feel safe from harm in their own home and this should never have happened.
“My thoughts are with the victim as he continues to recover and come to terms with this terrifying incident.
“This thuggish behaviour must be removed from our streets and I would urge anyone with information to contact the PSNI as soon as possible.”
