Four people including a police officer have been injured following a car crash and alleged stabbings in Sydney’s south, New South Wales police say.

Multiple calls were made to triple zero on Sunday morning after a two-vehicle crash at the intersection of the Princes Highway and Old Bush Road in Engadine at about 9am, police said in a statement.

“Officers … arrived to find a man – who appeared to be suffering stab wounds – allegedly running from the crash scene. He was taken into custody with the deployment of a Taser,” a spokesperson said.

A male police officer suffered a serious laceration to his left wrist during the arrest, the force said.

A woman – understood to be a passenger in the crashed vehicle – was found suffering multiple wounds.

A fourth person was also injured, NSW police said. “It’s unclear at this time what that person’s involvement is in this incident.”

All four people were treated by NSW Ambulance paramedics.

The NSW police minister, Yasmin Catley, said there was no ongoing risk to the community.

“That investigation is under way [and] I’ve been advised that the person of interest has been arrested,” she told reporters.

“There is no threat to the community. I want the community to know there is no threat whatsoever.”

The Princes Highway was closed in both directions and drivers were urged to avoid the area.
