POLICE have not ruled out charging four men who intervened in a domestic dispute, restraining a man who later died in hospital.
An internal police probe is also under way as the 38-year-old's death is being considered a death in custody.
The deceased man was held down by residents outside his Cairns home as they attempted to intervene when he allegedly attacked two women on Saturday night.
Police officers tried to revive the man, but he was pronounced dead in Cairns Base Hospital.
A male neighbour, who asked not to be named, said yesterday his wife watched the events from their driveway about 100m away.
He said his wife saw a woman and two young children leave the house followed by the man, thought to be her partner, who was yelling at her.
A male neighbour then intervened and tried to restrain the man before three other men went to his aid.
Another neighbour, who did not wish to be named, said she was shocked by the incident as the street was normally "very quiet".
Far North police Det Insp Bruno Asnicar said police could not rule out charges.
"It's an investigation," he said. "There're always *possible charges as a result of an investigation."
"It's just so early in the investigation that certainly no decisions have been made about any charges at this point.
"We've had a large number of people assisting us on the night and that was very encouraging."
