Lancashire Police said they have "looked at and discounted" the "potential criminal element" of the disappearance of Nicola Bulley.
Mum-of-two Nicola, had just dropped off her two children at school and was walking her dog, Willow, by the River Wyre in Lancashire before she disappeared on Friday, January 27. Emergency services and members of the public have now been searching for Nicola for a total of 11 days.
Police officers said they are working on the theory that the 45-year-old , who has been described by friends as a strong swimmer, fell into the river, but that line of investigation has been questioned by friends and family. In a press conference on Tuesday, February 7, Superintendent Sally Riley said the force still believes this is the case.
