A 58-year-old suspect is under arrest after at least four people, including a police officer, were injured in a bizarre fit of domestic violence that escalated into a knife attack Sunday in Sydney, Australia. The incident is the latest in a series of violence with knives in Australia’s most populous city, Reuters reported.

No one was killed in the attack although the assailant himself was apparently injured and received first aid on-scene. The fight occurred after two cars ran into each other on the road in the suburb of Engadine.

The attacker "was armed with what we believe to be a boxcutter," police superintendent Donald Faulds told a televised press conference, according to Reuters. One of the victims had a heart attack during the attack and she, along with others wounded in the incident, received medical care at St. George Hospital, the Daily Mail noted.

Other injuries included a stab wound in the stomach for a second victim and a broken arm for a third. “A male police officer suffered a serious laceration to his left wrist believed to have been incurred during the arrest,” NSW Police said in a statement.

According to a witness who talked to the Daily Mail Australia, the car crash and stabbing appeared to be two separate incidents because the people involved in the accident apparently took their argument outside of the car and about 600 feet farther up the road.

The New South Wales government, the state where Sydney is located, is increasing penalties for knife assaults after a series of attacks. Police can now use electronic metal detectors at shopping malls, sporting events and public transport centers to scan people who are not authorized to carry a knife.
