Police have promoted the Be A Nice Guy (BANG) campaign aimed at reducing anti-social behaviour over this year’s Hallowe’en and Bonfire Night period. Deputy Chief Constable of North Wales Police Ian Shannon said: “We wish for everyone to have a safe and happy Hallowe’en, but would like to remind people to have fun responsibly rather than disturbing others.” Their advice includes not knocking on doors where a ‘No Trick or Treat’ sign is visible.
