Australian officials are hunting for a shark that killed a teenager off Australia's southwest coast.

Seventeen-year-old Jay Muscat was spearfishing with a friend on Monday off Cheynes Beach, on the south coast of Western Australia state, when he was attacked. The state fisheries department says the shark was likely a great white.

Officials closed the beach and deployed equipment on Tuesday in an effort to catch the animal.

The attack comes two weeks after an 18-year-old man was killed by a shark while spearfishing on the Great Barrier Reef off Australia's east coast.
