Strathclyde police are trying to track down a man who impersonated an elderly woman to steal £11,000 from her bank account.
The man was disguised dressed as an elderly lady to withdraw the money at Royal Bank of Scotland branches in Glasgow and North Lanarkshire on 2 February.
The cash was stolen between 11:20 and 12:00. The police were alerted after reports of a “square-jawed” impersonator.
The 76 year old victim had been targeted in a phone scam where she was tricked into disclosing her pin number and handed over her bank card to a courier.
A Strathclyde Police spokeswoman said: "An extensive inquiry is under way after a cross-dressing rogue targeted an elderly lady.
"The hustle started in January when the elderly female received a phone call from someone telling her to phone the bank.
"As a result of subsequent discussions, the cardholder disclosed her pin number and made arrangements for a courier to collect her card."
Police are examining witness interviews and CCTV footage to try to trace the man.
PC James Ruddell, of Strathclyde Police, issued a warning over similar scams.
He said: "The actual bank card has no monetary value. If there is a problem with the card, the bank would ask you to destroy it and a new card and pin would be sent to you. No bank staff know your pin and they will never ask for it. No-one else should ever know your pin, not your husband, wife or children."
