Norfolk residents are being warned to be vigilant of cold callers claiming to be police officers who need help with an investigation.

Suspects have been calling homeowners stating they are from the police force and have said that either their bank cards have been cloned to purchase items or they need to assist in an investigation by withdrawing cash.

Calls have been received by a number of residents in the Norwich, Great Yarmouth and Gorleston areas.
