A crime scene was established on the cliffs of Dover Heights after the 46-year-old was treated for stab wounds this afternoon.
It’s alleged a 46-year-old man, believed to be a friend of the woman’s husband, knocked on the woman’s door before stabbing her around 3pm, leaving her with a severe chest wound.
Three builders working nearby heard the woman’s screams and rushed to the scene, disarming the alleged attacker.
The knife was dropped and the man allegedly fled.
A neighbor witnessed the aftermath of the incident.
“My understanding was she opened the door because he was familiar to her,” witness Marina Bassin said.
The three builders are being credited with potentially saving the woman’s life.
“There were three of them. They were so brave… extremely brave,” Bassin said.
“She was also extremely brave, screaming for help.”
Paramedics stabilized the woman before taking her to St Vincent’s Hospital in a critical condition.
“This was a very traumatic scene to arrive at with a significant, life-threatening stab wound,” NSW Ambulance Inspector Giles Buchanan said.
“Paramedics administered IV fluids, stemmed the bleeding and provided pain relief to stabilize the patient.
“Stabbing wounds are generally confronting incidents and this patient has suffered a very serious injury.”
The alleged attacker was tracked to Bondi Beach and arrested this afternoon.
