Dud notes

Mr Diver said: “I have spoken to the police about this and they have told me that there is an ongoing low-level problem with counterfeit notes here in Derry. However, they have also said there are spikes in that activity as well.

“The important issue is to raise awareness of the note and the denomination – which is an Ulster Bank £10 note.”

He advised businesses and people throughout the city to ensure that they check the notes they receive.

“I realise that staff and people in general are often busy and that it is not always easy to take the time to check banknotes properly, however those involved in this type of crime often rely on this very fact.

“I would urge anyone in possession of a banknote they believe to be counterfeit to retain it and pass it on to the police as soon as possible,” he said.
