Detective Inspector Bolton is an officer for the Bradlington Police and only appears in Episode 9, A Quiet Night In. He is investigating a case of stolen property; designer brand Sinclair clothing. He arrests Rhydian and tries to keep him locked in a cell over night; except it's full moon. When the Smiths find out, Maddy comes up with the idea to tell the police officers that Rhydian has a severe case of Clinical Lycanthropy, which is when you think you are turning into a werewolf. They let Rhydian go on no charge when they see him scratching and howling.
Detective Inspector Bolton is portrayed by Joe Caffrey.
