Three Hampshire pensioners in their eighties have been conned into giving £25,000 in total to fraudsters.
The three victims involved were called by someone pretending to be a police officer investigating various payments in their bank accounts.
They were asked to take out money from their banks and check the serial numbers only to be told that it was counterfeit and a courier was coming to collect it.
Phil Rogers, from Hampshire Constabulary, said: “We would never request anyone to withdraw of handoff money, if anyone receives such a call, they should contact us.”
Hampshire Police are urging members of the public to warn their elderly relatives about these fake calls.
