COFFS Harbour police have called for public assistance over a violent home invasion where a gang of armed offenders seriously injured a family.
The attack happened in an industrial unit in Cook Dr on Father's Day and left a 41-year-old man with life threatening injuries.
Police said the man's girl friend, 27, and his son, 18, were also hospitalised.
The home invasion happened on Sunday, September 4 about 11pm.
The three victims were asleep when the offenders entered the premises through an unlocked front door.
Police said the man was hit repeatedly to the head with a blunt object while he was asleep.
His girlfriend was dragged out of bed and attacked, before the man's son was chased down and attacked from behind.
He was knocked unconscious after he was struck repeatedly to the head with a weapon.
Witnesses say the intruders fled the scene in a sedan while looked similar to an older model Ford or Commodore.
All three victims were hospitalised before the man was airlifted to Newcastle with life threatening head injuries including skull fractures and cranial bleeding.
His son received 26 stitches for two large wounds and the female was treated for bruising.
Detective Craig Semple who is leading the investigation is appalled at the ferocity of the attack.
"People have a fundamental right to feel safe within their own homes," Detective Sergeant Semple said.
"To have your home raided and to be seriously assaulted while you are sleeping in your bed is absolutely shocking.
Police are investigating a number of possible motives and they believe at least three and as many as five male offenders took part in the attack.
Detective Semple said some information has been forthcoming, several suspects have been questioned and forensic evidence is being examined, but police need more help from the public.
"Although we have made some progress, we really do need more witnesses to come forward with information.
"If anyone saw a vehicle speeding away from the scene or is aware of the identity of the attackers we are very keen to hear from you," he said.
Information can be given anonymously to Crimestoppers on 1800 333 000.
