A surfer is feared dead after being attacked by a shark in shallow water on a remote beach in Western Australia, police said on Tuesday.
A 30-year-old man from Melbourne was reported missing on Monday after witnesses saw a struggle and heard screams at Wharton Beach, a remote area around 800 km (497 miles) from the state capital, Perth.
A surfboard with bite marks was later recovered from the beach.
Police believe the man was killed during the attack after failing to locate his body.
“The family has been notified. I suspect it will be a recovery of a body if we can find it,” Western Australia Police Commissioner Col Blanch said in an interview with Perth radio station 6PR on Tuesday.
Drone footage shot by a witness captured a shark swimming away from a large cloud of blood close to the shore, he added.
