Shortly after midnight last night, five masked men broke into a house in the Rosapenna Street area.
They ordered a man in his 50s to come down from an upstairs room.
He was then set upon downstairs by the gang who attacked him with hammers.
The victim sustained injuries to his hands and legs. He was treated in hospital but his injuries are not thought to be life threatening.
Anyone with information is asked to contact detectives at Antrim Road CID on 0845 600 8000 or Crimestoppers on 0800 555 111.
