Searches for missing mother Nicola Bulley have entered an 18th day after her heartbroken husband said his "gut instinct" is that she is not in the river.
Lancashire Police said officers are keeping an "open mind" while continuing to appeal for information about Nicola, who disappeared on January 27 while walking her dog in St Michael's on Wyre.
The force is continuing to search the River Wyre towards the sea at Morecambe Bay, working on one hypothesis that the 45-year-old, from Inskip, could have fallen in.
