The incident took place in the Gibson Park Gardens area of East Belfast on Friday night.
Councillor Michael Long said: “It is extremely distressing to hear of such a brutal attack taking place within our local community and I must condemn all involved.
“Everyone has the right to feel safe in their own home and my thoughts are with the victim, his friends and family as they attempt to come to terms with and deal with the aftermath of this heartless attack.
“I would urge anyone with information to contact the PSNI as soon as possible, ensuring those behind this attack are removed from the streets and dealt with before the courts.”
