Shark trapped and killed in WA after surfer loses leg in attack

Drum lines were set in the wake of the attack on Ben Gerring and a 4.2m-long great white was caught shortly afterwards

Western Australia's fisheries department has trapped and killed a large great white shark in baited drum lines close to the site where a surfer suffered life-threatening injuries in an attack.

The authorities took samples from the 4.2m-long shark to see whether it was responsible for the attack which left a 29-year-old fly-in fly-out worker, Ben Gerring, fighting for his life.
