Giant man-eating catfish found in Guangdong reservoir?

We found the following email in our mailbox the other day. Apparently it's been making the rounds on the Chinese-language internet.
Each year, a few people will be drowned mysteriously in Huadu's Furong Reservoir. It was not until recently when the brother of a certain official went swimming in the reservoir with his friend and were drowned that the secret was unravelled!
It's a 3 metre long man-eating catfish whose head alone is 1 metre wide! After cutting up the catfish people were surprised to find the remains of a man inside!
Because this was a huge incident, and the local government was afraid of the impact on local tourism, they imposed an embargo on the news, but people came away with these pictures taken on their cell phones of the man-eating fish!
Swimming in the reservoir is now forbidden because it is feared another similar man-eating catfish is still lurking in the waters.
