Police are urging north Norfolk householders to be vigilant after reports of bogus callers.

The first incident happened on Monday September 13 in Morley Road, Sheringham, where a man called at a property claiming to be from a phone company and asked permission to improve a telegraph pole outside. A second incident happened at around 1.30pm the next day when someone called at a property on School Road, Erpingham, claiming to be from a utility company but they were unable to provide identification.

Norfolk police advise people to use a door chain or viewer and not to open the door to anyone unexpected or unknown and to ask for identification and check it with the caller's company. Report anything suspicious to police on 0845 456 4567.
