An elderly couple were targeted in a suspected fraud.
A man purporting to be from HSBC attended a house in Plessey Road in Blyth to tell the couple they were due a refund on their account, returning two weeks later at 5pm on Wednesday, July 29.
The man is described as being middle aged, mid to late 40s, dark average length hair, 5ft 10ins to 5ft 11ins tall, smartly dressed and possibly driving a silver car.
Officers are now appealing for anyone who saw anyone acting suspiciously in the area at the time to get in touch with police and are warning residents in the area to be on guard against bogus callers.
The appeal is part of Operation Strongbow – an initiative which targets doorstep crimes and distraction burglaries.
A police spokesperson said: “Callers who turn-up unannounced should always be treated with caution.”
