Swimmer killed in shark attack in front of horrified beachgoers

A man was killed by a shark as he swam off a Western Australian city beach Friday while beachgoers watched in horror.

Boats and helicopters searched the ocean off Sorrento Beach in Perth's northern suburbs after the late-morning attack, a police statement said. Police would not say whether potential remains had been found.

But police were confident the "swimmer died as a result of the attack," the statement said.

A witness to the attack, identified only as Darrel, told Nine Network television that the victim had been swimming with a now traumatized friend.

"I was just shocked. I mean, I feel for his mate. He's apologized and said 'I didn't save my mate,'" Darrel told Nine.

Witness Ingrid Mitchell, who swims at the beach daily, said to Nine: "How do you just watch someone be mauled to pieces in front of you, basically? It's pretty hard."

"My friend said, 'Jac, I think there's been a shark attack,' and I looked out to the ocean and I could see a pool of blood," beach walker Jacqui Rapaic told Australian Broadcasting Corp.

Local Ryan Rowe told The West Australian newspaper that he reached the beach soon afterward and was told by an onlooker "someone had been bitten by a shark."

"I couldn't believe there was that much blood (that had) come out of a human body," Rowe said.

Authorities closed the beach to swimmers. Witnesses described the swimmer as a man in his 60s but police did not identify him further.

In a separate shark attack, a surfer sustained a serious leg injur y Monday near Geraldton, about 400 kilometers (250 miles) north of Perth.

There have been at least five fatal shark attacks in Australia this year.

A 12-year-old boy died after he was bitten by a shark while swimming in Sydney Harbour in January. The attack that killed the boy was one of four recorded in the span of two days , which prompted officials to close dozens of the city's beaches.

Three divers were also fatally mauled in separate incidents between May and June — two in Western Australia and the third in Queensland.
