A message sent on behalf of Lincolnshire Police and Lincolnshire Fire and Rescue:
Over the next few weeks we'll see more spooky decorations and parties in our communities in celebration of Halloween and Bonfire night - and we hope you'll be having fun.
We want to help everyone to celebrate safely, while being mindful of those who may wish to enjoy a quieter few weeks, which is why we're offering a free "No trick or treaters" poster which can be downloaded and popped in your window to let people know if you'd rather they didn't knock on your door.
We're also encouraging parents and guardians to explain what that means to children so that elderly members of the community or vulnerable people are not frightened by unwanted callers.
The poster is being offered as part of #OpCauldron.
People unable to download and print posters can collect one from the front desk of their local police station. Download them here: https://www.lincs.police.uk/police-forces/lincolnshire-police/areas/campaigns/campaigns/enjoy-halloween-and-bonfire-night-safely/
