Ms Bulley’s disappearance attracted massive public interest, especially from amateur sleuths and social media video-makers, who have been coming up with their own theories.
Police have said these people and their actions have “distracted significantly” from the official investigation and some have since been arrested.
A full independent review has been commissioned into Lancashire Police’s handling of Nicola Bulley’s disappearance with the College of Policing overseeing the investigation.
