Hampshire police are joining forces with the Post Office to stamp out doorstep conmen who prey on the public, particularly pensioners.

The move comes as an elderly woman was targeted in the 'Roman' estate area of Chandler's Ford by a rogue who tried to trick his way into her home.

The conman, who called at the house in the Clausentum Close area just after 6pm on Monday, claimed he was a surveyor for the government checking for damp.

He wanted access to all parts of the house but, as an Eastleigh police spokesman said: "The elderly lady had the good sense not to let him in."

But police have warned householders to be on their guard.

They have also issued a description of the suspicious caller who was aged 45 to 50 and 5ft 10in tall.

He has dark wavy hair and is clean shaven but with a 'five o'clock' shadow. He was driving a red J registration Peugeot.

Determined to crackdown on doorstep conmen, Eastleigh police have teamed up with the Post Office by launching a poster and leaflet campaign.

Eastleigh police division has got the backing of 21 post offices in the area for the campaign which runs throughout November.

Posters will appeal for people to report confidence trickster crimes and will offer support to victims.

And leaflets on post office counters will offer advice on how to foil the conmen.

Eastleigh crime Reduction Officer Barbara White said: "We know that victims, many of them elderly, are reluctant to come forward.

"Often they are embarrassed that they have been taken in."

She added: "It is vital that police have information about the people who are tricking residents to steal their money, valuables or pension books, because this is a most despicable crime."

To foil doorstep conmen residents are advised to:

Put a chain on the door before opening it.

Be suspicious of all callers until you know who they are.

Always check identification by calling the head office and not a number given by the person on the doorstep.

Don't be fooled by sob stories like children looking for lost pets.

Report all suspicious callers to police immediately.

Barbara added: "Our plain and simple message is - if in doubt keep them out."
