Officials suspect that a shark attacked a 64-year-old man who disappeared while swimming off one of the Australian west coast's most popular beaches.
Police Senior Sgt. Denise Grant told Australian Broadcasting Corp. radio that Bryn Martin disappeared Monday while swimming toward a buoy off Perth city's central Cottesloe Beach.
Grant says police divers found Martin's torn trunks hours later on the sea bed near the buoy. She says shark experts agree the tearing is consistent with a white pointer attack.
Australia's last fatal shark attack was in April when a surfer lost both legs off a beach south of Perth.
