Police are making people aware of a cold calling scam where fraudsters try to buy vulnerable items at a fraction of the price.

It comes as an elderly resident let a man into her Speldhurst home on Tuesday, after he asked if she had any old books for sale.

Once inside, the caller took an interest in a number of items, offering to buy pieces of jewellery.

He finally left when the woman told him they were not for sale.

Last month a similar incident was reported in Wilman Road, Tunbridge Wells.

Inspector Richard Pringle said: "Never let someone you don’t know into your home. We have had incidents in the past where victims have been tricked into selling valuable possessions for a fraction of their value, or even had items stolen from them.

"Sadly, criminals will often target elderly and vulnerable residents and we are also asking relatives and neighbours to be alert to any suspicious activity."

Police are warning residents to keep doors on a chain if someone turns up unexpectedly, or check through a window if you don't have a door chain.

Additional measures including making sure doors are shut and locked.

A spokesperson from Kent Police said: "If you have any doubts about whether a caller is genuine, ask them to leave and come back at a time convenient to you and when you've had a chance to ask someone to be with you. Call police if you suspect cold callers may be bogus

"Be aware of methods used by criminals to distract you such as being asked to make a telephone call, to use your toilet, for a glass of water or being asked to check water or gas supplies."

Report any suspicious behaviour by calling 101, or emailing Csu.tunbridge.wells@kent.pnn.police.uk If a crime is in progress call 999.
