Residents of Borough Green are being warned to be wary of bogus callers asking for money.
Police received reports that a man and woman, in their 30s, called at a home in Maidstone Road on Sunday, claiming they had run out of petrol.
They reportedly told a homeowner they had broken down, before asking for money to buy fuel.
After being given a small amount of cash they were seen to walk past a nearby petrol station in the direction of Crow Hill.
A neighbourhood watch representative for the area says a string of similar incidents have been reported .
Inspector Sonia Lassnig said: “Although it is possible that these two people may genuinely have run out of petrol our advice would always be to never give money to strangers who knock on your door.
“Most people who call at your home will be genuine. But there are those who turn up unannounced whose only intention is to deceive people out of their money.
“It is likely that they may only ask for one or two pounds in the hope of seeming more genuine. But by pulling the same scam on lots of different homes they can soon make a lot more than that.”
If you are at all concerned about a caller at your doorstep, call Kent Police on 101, or 999 if it is an emergency.
