Halloween trick or treaters are being asked to respect people who do not want to be visited.

And Norfolk police has put a poster on its website which people can download if they want to welcome youngsters to their door on Sunday.

Chief Inspector Gavin Tempest said: 'We want everyone to have and enjoyable Halloween and understand that going trick or treating is an exciting tradition for youngsters. However, Halloween can be a distressing time of year for some vulnerable members of the community and we would ask trick or treaters to respect the wishes of those who choose not to mark the occasion.'

Youngsters heading out to trick or treat are also being safety tips including not to go out alone, to get permission from parents, stay on the doorstep and do not enter houses, do not talk to strangers on the street, stay in well-lit areas and carry a torch, and 'although Halloween is about looking spooky, be careful not to frighten the elderly.'
