A bogus caller pretending to be a window cleaner is preying on elderly residents in Medway.

In one incident he tricked his way into a woman’s house in the City Way area of Rochester and stole £100 from her purse.

Medway Council’s trading standards team have issued a warning to householders to be on their guard.

Four cases have been reported in the Strood and Rochester area in seven days.

Cllr Mike O’Brien, in charge of community safety, said: “If you are concerned about a cold caller who has knocked at your door please report the matter to the trading standards helpline on 08454 040506 and if you feel threatened or intimidated report the matter to the police.”

The advice from the Home Office is that you should Lock, Stop, Chain and Check to protect yourself from being a victim of crime.

Lock – Keep your front and back doors locked, even when at home.

Stop – Are you expecting anyone?

Chain – If you decide to open the door, put the door chain on first.

Check – Ask for the caller’s ID and check it by phone.
