No 'arm done

Mr Chang had his arm through the crocodile's enclosure to administer the anaesthetic.

Believing the animal was successfully anesthetised, Mr Chang tried to remove the syringe, but the crocodile suddenly turned and bit off his left arm, holding it in its mouth.

As the vet was rushed to hospital, zoo employees tried to retrieve the severed arm by shooting two bullets at the crocodile's neck.

Although the bullets failed to penetrate the reptile's hide, the effect was enough to cause it to drop the arm.
