Ammon News - Four people including a police officer were injured in a stabbing attack in Sydney early on Sunday, police said, the latest in a series of knife assaults in Australia's biggest city this year.

A man who ran from the scene has been taken into custody, police said in a statement. There is no ongoing threat to people in Sydney, said New South Wales state Police Minister Yasmin Catley.

Police said no one was killed in the attack, which came after a "domestic-related" incident in a car that collided with another vehicle in the southern suburb of Engadine.

The attacker "was armed with what we believe to be a boxcutter," police superintendent Donald Faulds said in a televised press conference.
