Fake £50 notes have been used at businesses in the Highlands, police have warned.

The counterfeit notes were handed over in Kingussie and Newtonmore on Thursday,

It follows similar incidents in Nairn last week.

All the notes are designed to look like they have been issued by the First Trust Bank, based in Northern Ireland.

Each bears the same serial number of BA389087.

The incidents in Nairn involved two men, described as speaking with Irish accents, while the more recent incidents involved a woman.

Preventions and interventions officer Constable Katy Duncan said: "We are urging members of the public, particularly retail workers who deal with cash sales, to check bank notes matching this description before completing the transaction.

"The notes which have been recovered so far do look plausible at first glance so it is important you check any notes matching this description thoroughly, including checking for this identical serial number.

"Any such notes should not be accepted and police should be contacted immediately.

"Anyone who suspects they may have received one of these notes or who has information about those using them should call police on 101, quoting NM3028/18, or Crimestoppers on 0800 555 111."
