Police have issued further warnings to retailers in Norfolk after reports of fake Northern Irish notes in circulation in the county.

There were a number of reports on Wednesday of fake Northern Irish £20 and £50 notes being handed over at stores in the north Norfolk, Kings Lynn and Great Yarmouth areas.

Three people, a 38-year-old woman, an 18-year-old man and a 16-year-old girl, were arrested in Great Yarmouth on Wednesday in connection with an incident in which counterfeit notes were used at a shop in the town.

They have all been released on police bail pending further enquiries until September 30.

• Retailers are being urged to be vigilant and to contact police on 101 if they have received, or come into contact, with any counterfeit notes.
