A MAN has been left with multiple head injuries from a Coffs Harbour home invasion.
The 41-year-old was in a stable condition at Newcastle's John Hunter Hospital on Monday night, where he is being treated for a suspected skull fracture, bleeding on the brain and possible brain damage.
Forensic police pored over the crime scene at premises in Cook Dr on Monday afternoon where they taped off a Mitsubishi van that had smashed windows.
Emergency services were called to the residence about 11.20pm on Sunday.
Police have been told a 'number' of men not further described stormed the address as the 41-year-old slept in bed with his 27-year-old partner.
The men allegedly assaulted the 41-year-old with a weapon, which detectives have also not further described.
He was rushed to Coffs Harbour Health Campus and later transferred to John Hunter Hospital.
The 27-year-old tried to flee through a window but one of the men dragged her back inside, bruising her arm, according to investigators.
Police say the assailants also assaulted the man's 18-year-old son, who was subsequently treated for a cut to his head.
