“We would advise homeowners not to accept offers of work from door to door tradesmen. Instead, if you need work to be done in your garden or home use a reputable recommended business.
“Be particularly wary if the person will only accept cash. If you are at all concerned about someone calling at your door do not hand over any money and contact police with details.”
You can report suspicious activity to the police on 101, or call the charity Crimestoppers on 0800 555 111.
