Officers were called to Alpha Road at around 11.50pm on November 27, attending alongside ambulance services, where they found the victim.
He was taken to hospital for treatment, where he remains in a non-life-threatening condition.
Detectives believe that the man had been at a party in the area prior before being attacked.
This party was attended by a large number of people and officers are keen to speak to any attendees who may have witnessed anything suspicious.
Detective Constable Lottie Williams, leading the investigation, said: “It is really important that we speak to anyone who attended the same party as the victim to fully understand the sequence of events that let up to this incident.
“You can share what you know anonymously via independent charity Crimestoppers who won’t record any personal caller information. Please get in touch however you feel comfortable and tell us what you know.”
