Specialist underwater rescue teams have joined the search for missing Nicola Bulley. The mother-of-two's family had approached a private company and asked them to help police.
Officers have 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. Lancashire Police has consistently said that there are no signs of any third-party involvement in her disappearance.
Here is what we know as the search reaches its 10th day.
