An elderly woman has been caught out by a scam involving counterfeit notes.
The woman was walking towards Asda along Iliffe Way, Stowmarket, on October 24 when a dark coloured car pulled up alongside her.
Police have said the man driving the car asked if she would swap a £20 for two £10 notes, which she did.
However when she checked the £20 note shortly afterwards it was found to be counterfeit.
The man is described as well built with a round face, short dark hair, clean shaven and wearing a dark coat.
There was a female passenger in the front of the car possibly wearing a skirt.
The vehicle is described as possibly dark grey or dark blue and looked around 15 years old.
