Burglars in Somerset are posing as bogus "Waterboard" and fake Dyno-rod officials to trick their way into homes before stealing cash, purses and wallets. 

That's the warning from police, who are urging residents to keep back doors locked, use doorchains and always ask for ID when answering the door.

The force also says some thieves are even using children to distract the homeowner by claiming they've lost a ball in their garden.
