A police spokesman said the investigation is in the early stages but Police can confirm that one person who lives at the address was taken to hospital with "serious but not life threatening injuries".
The scene was secured and Police are conducting a scene examination today.
"One of the offenders is believed to have left the Kennedy Road area on a bicycle and may have cut themselves during the incident," they said.
"Initial inquiries suggest this is an isolated incident and there is no reason for the wider community to be concerned."
