A woman has been stabbed several times to the upper body in the New South Wales Hunter region.
Emergency services were called about 10am to Segenhoe Street at Woodberry near Maitland where they found a 39-year-old woman with multiple stab wounds.
She was treated at the scene and later transferred to John Hunter Hospital in a serious condition.
A 37-year-old woman was arrested at the scene and taken to Raymond Terrace police station for questioning.
Police officers went from door to door speaking to neighbours, who recalled hearing an argument before the alleged incident.
Police say the women are known to each other, but there is no evidence to suggest they were in a domestic relationship.
Chief Inspector Rob Post, from Port Stephens-Hunter police, said officers were yet to establish if there was a motive behind the attack.
"There's been a number of witnesses identified," he said.
"We are appealing for anyone who has information to contact police, and anyone who might have any dashcam footage or CCTV footage.
"I believe this is an isolated incident and no one should be concerned."
