Bird flu bandits?

May be another rumor.
Bizarre mail going around, it appears that folks are answering the door to people claiming to be from the health ministry,after being told they have to have a vaccination for bird flu they are pumped full of sedative and their apartment robbed.

Kinda cunning in a weasel sort of way I thought, though you would have to be pretty stupid to fall for the con.

"Excuse me sir I'm from the health ministry and so are my friends, and I want to jab you full of a bird flu vaccine (that doesn't exist)"

"doh ok"
