A 33-year-old man has been charged with murder after his girlfriend's father was fatally stabbed at a Christmas Day gathering in Queensland.
The disturbance started inside a North Ipswich house before people moved into the front yard, Detective Acting Inspector Heath McQueen told reporters on Saturday.
He said police were called to the property about 11.40pm on Friday.
They found a 53-year-old man with "significant wounds" in the front yard.
Police and paramedics tried to resuscitate him.
Officers believe there was an altercation between two men which resulted in the older man being stabbed in the front of his body.
Acting Insp McQueen said there appeared to have been "some sort of domestic dispute ... which unfortunately has escalated to a point where significant violence has occurred and a male person has lost his life".
Police confirmed the 33-year-old man's girlfriend is the daughter of the man who died.
Officers were also searching for evidence at a house in Woodridge, south of Brisbane, where the man was arrested about 5am on Saturday.
He was charged with murder, assault occasioning bodily harm (domestic violence-related) and wilful damage, police said.
The man has been denied police bail and is due to appear in Ipswich Magistrates Court on Monday.
