Man Punches Shark to Fend Off Terrifying Attack on Teen, on Video

A fearless guy ran up to a shark and punched it in the face in Australia just moments after it clamped onto a teenager -- and it was all caught on camera!

Terrifying footage at Cabarita Beach in New South Wales Sunday shows a man charging at the 7-foot-long shark lurking near the shore, while others rush the injured teen onto the sand to safety.

A heroic move, but the boy had already been injured on his right arm, wrist, and leg. Still, it worked -- the shark backed off!

Once the shark was gone, a makeshift stretcher was fashioned from a surfboard, and the teen was rushed to safety before being airlifted to Gold Coast University Hospital. The teen is in serious but stable condition.

A second helicopter was sent out to track down the shark, but no luck -- they came up empty.
