The incident happened in the Maple Drive area of the town in the early hours of Thursday.
Councillor Yvonne Boyle said: “I must condemn this horrifying incident, which has left the community in shock.
“The fact this man was chased only to be again assaulted makes it all the more chilling.
“Those behind this incident do not speak for the whole community and I would urge anyone with information to contact the PSNI as soon as possible.”
