A 77-year-old woman has been arrested in connection with a UK-wide telephone scam in which a Staffordshire pensioner was duped into parting with £8,000.
The woman was detained by officers in Paignton, Devon, on suspicion of money laundering.
She was given police bail until December 12 while officers continue to investigate reports that pensioners nationwide have been targeted.
Earlier, Staffordshire Police said an elderly woman had been conned after being contacted by an organisation which claimed she had won between £ 120,000 and £240,000 in an international lottery.
In order to receive the prize, the victim, from Stafford, was asked for £8,000 to cover taxes.
Officers investigating the case contacted colleagues at Devon and Cornwall Constabulary who made the arrest.
A Staffordshire Police spokeswoman said: "It has transpired that other elderly people across the UK have been conned in a similar manner."
