A spokesperson for St John’s Ambulance WA said they had received a call at 10.03am of a shark bite. Lifeguards were earlier seen hurrying other beachgoers out of the water. One eyewitness told West Australian a man came “flying” over to him, screaming that he had seen a “massive shark”. Ivana Busic said: “I was in the area surfing when the alarm went off and we heard there was a shark in the water. “Everyone ran out of the water. I am pretty shocked.” Other witnesses suggested the beast may have been a great white. The beach remains closed as well as nearby Leighton and Cottesloe beaches.
