Dont know if anyone recalls it, but about 8 years ago an elderly chap who lived on his own in Bognor Regis had nearly £100k taken from him by a couple of pikeys who 'worked' on his house for about a year. Every time they did a job they took the guy down to the bank where he withdrew a few thousand and then paid them in cash.
In actual fact they had done nothing and it was only when his son turned up and asked him for some money that it came to light that all his savings were gone.
It was on the local news at the time. The two in question were caught and did get a couple of years each.
I'm afraid this sort of thing happens everyday and you ' the public'.. never get to know about it.
Most of my working day at that time was spent improving security in vulnerable peoples properties. It was fairly normal to attend 2 distraction burglaries a day, not to mention countless snatched handbags.
The Police wont be interested and what do you think the Council have to do with it. Trading Standards do not check the quality of work a window cleaner gives.
If the elderly man lets them in there is little you can do.
