Five men have been jailed following a string of phone frauds, including one in Steeple Bumpstead where three members of a family were tricked out of £7,000.
The gang, jailed for a total of 17 and a half years between them, stole more than £40,000 after they tricked 11 people into handing over bank cards and PIN numbers.
They made 1,200 cold calls across several counties.
In all the offences they posed as police officers or bank staff and told their victims that their bank accounts had been infiltrated by thieves.
They usually claimed to be from the Metropolitan Police and used the names DC Lescott, DC, DS or DI Rogers or DI Maguire.
The tricksters claimed they needed to do forensic tests of the victim’s bank cards, PIN numbers or cash.
