Shoppers in Preston city centre are being warned about a scam at cash machines.Advertisement
A number of males have been approaching elderly women who are drawing out money in the city centre.
They present them with £20 and a receipt suggesting that it has just been withdrawn, and claiming they need two £10 notes.
Preston Police say the men then ask to exchange the notes, but the £20 is a fake note.

PCSO Stephen Connelly said: “Please be cautious of any person approaching you at a cash machine.
“We’re working to release CCTV of those we think are responsible.”
Police are asking anyone who sees anything to call them on 101.
