A search continues for a 57-year-old man reported missing at a West Australian beach where it’s feared he may have been attacked by multiple sharks.
The incident happened about 10am on Saturday at Port Beach in the suburb of North Fremantle, police say.
Two teenagers on a boat saw what they believed was a shark attack and called emergency services.
WA Police Acting Inspector Troy Douglas said the search for the missing man would continue for as long as possible on Saturday.
It will resume at first light on Sunday if he is not found.
The man regularly swam at the beach, Insp Douglas said.
He said police were unable to confirm how many sharks were involved in the attack but said it was “obviously at least one”.
Insp Douglas said the teenagers “made a fantastic effort” and “reacted really, really well” by alerting emergency services and providing information to assist the search.
All beaches in the area have been closed.
