POLICE warned home-owners, particularly the elderly, to be on their guard today after receiving reports that bogus security salesmen were knocking on doors in the Ryedale area.

Police were alerted after receiving two calls this week from residents living in Malton and Norton. In both cases the women became suspicious when they were offered "reliable alarm systems" by two men - thought to be in their twenties - unable to produce identification when questioned.

PC Terry Triffitt, community safety officer for the area, said the men - who are believed be part of an organised team - often say they are from the "police crime squad".

"The problem is these men often target the elderly because they're considered vulnerable and gullible," said PC Triffitt. Although he was unable to confirm what their motives were, PC Triffitt added that in most cases door sales men were simply out to sell "inferior products for outrageous prices".

"The goods usually don't fit properly, they're not very good value for money, and they're unreliable.

"Claiming they're from the police is a bold statement because we only approve alarm systems checked by independent inspectorate organisations. "Everyone should be on their guard when approached by doorstep sales men; reputable companies don't have to knock on doors."

PC Triffitt has issued the following advice for people who come into contact with door to door sales men:

* Never let them in the house.

* Ask to see their identification

* Ask the salesman if he can provide you with a list of police rules for homeowners with alarms. And a written quotation confirming that the alarm and company are acceptable to the police.

* Obtain written quotations from at least three other alarm installers.

Anyone who wants any advice on home security, or has seen anyone acting suspiciously, should contact PC Terry Triffitt on Malton police 01653 692424.
