EARLIER: A neighbour who phoned police after an alleged stabbing in Maryborough says he heard a loud argument with banging and yelling on Wednesday night.
"I was going to come out and I heard a bloke say 'he's been stabbed' or 'you've stabbed me', something like that," he said.
"And then I called the police ... I heard this morning the bloke who did it jumped the back fence."
The man said police and ambulance crews arrived shortly after his emergency call.
