A4.5-metre white shark attacked and killed a swimmer on the beach of Little Bay in Sidney, Australia, with the deadly attack being witnessed by several people and recorded on camera.

Witnesses heard the swimmer's terrified screams, but they could do nothing to save the life of the 35-year-old man from Wolli Creek.

"Someone just got eaten by a shark. Oh man! Oh no! That's insane. That's a great white shark," a fisherman is heard shouting, according to Mirror.

Meanwhile, a New South Wales (NSW) Ambulance spokeswoman indicated that "unfortunately this patient had suffered catastrophic injuries and there was nothing paramedics could do."

Attacked by white shark

After watching the footage, the NSW Department of Primary Industries confirmed that the swimmer was attacked by a white shark.

"Based on footage provided by the public, including eyewitness accounts, DPI shark biologists believe that a white shark, at least three metres in length, was likely responsible," a DPI spokesperson said.
