Pensioners in Northamptonshire are trying out a new device aimed at stopping bogus callers.

The "granny boot" is a simple wedge on the end of a pole, but can be used to prevent unwanted visitors pushing doors open.

The gadget, made by people on community service, has been given to 150 elderly residents in a trial scheme across the county.

Community Safety Officer Terrie Watson said: "The granny boot is a simple device to use."

She added: "When placed against any inward-opening door it should stop unwanted callers from entering the home before their identity is checked."

One woman signed up for the trial is 86-year-old Gladys Barnett of Irthlingborough.

Five days ago, she became the 250th victim since April of a distraction burglary in Northamptonshire.

A youth called at her home and said he was from the local church, then pushed his way inside and stole her handbag.

She said: "I've been sitting here and thinking, 'I should have done this, I should have done that' - but I didn't.

"I realise how easy it is."

If the trial is a success, hundreds more so-called granny boots will be produced.
