There have been recent incidents in the Heckington and Helpringham areas where people are knocking on doors with the intention of selling paintings in their possession.  The sellers may claim to be deaf and will show a card which explains what they are selling. Please note that this card is NOT an official form of ID. It is also possible that the paintings may actually be photocopies. If you are visited by such people could you please report the incident to the Police on 101 or 999 in an emergency. PLEASE TREAT ALL COLD CALLERS WITH CAUTION.
