POLICE have arrested three men who they believe conned thousands of pounds from Solihull and Birmingham householders by falsely claiming their properties were infested with rats.
And detectives suspect there may be more residents who are simply not aware they have been victims of fraud.
The scam involves men, posing as officials, calling at a house claiming that a child has been bitten by a rat and they need to inspect.
They then claim the house is infested with rodents and will be condemned unless it is treated immediately, at huge cost.
Police said the latest case involved an elderly victim handing over £27,000 for work which was not needed.
This week three men, a 35-year-old from Chelmsley Wood, a 47-year-old of no fixed address, and 16-year-old boy from Tyseley were arrested on suspicion of fraud.
Anyone who thinks they may have fallen victim to the scam should call 101 and ask for Det Insp Gary Dring.
