Trick or treaters have been urged to only visit homes where people are displaying a poster which says they are welcome.
Police have produced a poster for elderly or vulnerable people, or those who simply would rather not be involved, to display in their windows to show whether they wish to take part.
One side says Trick or Treaters Welcome, while other side's message is No Thanks to Trick or Treaters.
