Police have been given the power to break up groups interfering with the search for Nicola Bulley in St Michael's on Wyre, after reports of amateur sleuths filming properties and uploading them on social media.
The dispersal order has been granted as the focus of the major search for the missing mother-of-two shifted towards the sea.
Lancashire Police said the powers were issued on Wednesday night after reports that people had come to the village from outside the county to film.
