Two police officers have reportedly been stabbed and an offender shot dead in an incident in South Australia's mid-north.
Police have confirmed they responded to the high-risk incident at Crystal Brook.
They say paramedics are on the scene with multiple people injured.
A medical retrieval helicopter was also dispatched to the town, about 200 kilometres north of Adelaide, just before midday on Wednesday.
It was believed one police officer suffered serious stab wounds and was being airlifted to the Royal Adelaide Hospital.
The second officer suffered minor wounds.
Media reports said they had attended the house in relation to complaints about the occupant's dog.
SA Premier Peter Malinauskas said he had spoken to Police Commissioner Grant Stevens in relation to the incident.
"My thoughts are with the two injured officers and their families," he said.
"Our police put their lives on the line every day keeping us safe, for that we are forever grateful."
