Piranha hunt under way after attacks in Chinese river

A hunt has begun for piranhas in a river by the Chinese city of Liuzhou, after two people were bitten in the water over the weekend.

Usually indigenous to South American rivers, it is suspected some of the flesh-eating specimens may have been released into the lake by people who had smuggled them into the country as pets.

Local authorities have now announced a reward of $160 to anyone who catches one - dead or alive.
