People in Norfolk are being warned to be on the look out for rogue traders knocking at their door.

Police received reports of two men who called at several homes in Wymondham yesterday evening at about 7pm enquiring about utility bills.

One was Asian and one white, both in their mid twenties and wearing a white shirt and black trousers.

A police spokesman said: 'We are unsure at this stage if they are genuine or not. Police are investigating.'
