A shark killed an American man Saturday off the coast of Western Australia.
According to police, a witness saw a "large amount of bubbles" before the man's body floated to the surface with fatal injuries, reported Sky News.
The 32-year-old man, whose identity has not yet been released, was diving alone, reported Sky News. He was living in Australia on a work visa.
Witnesses spotted the shark and said that it appeared to be a 10-foot great white, reported ABC News.
This is the second shark attack in Western Australia within 12 days.
