A dog walker tracked down by police investigating the disappearance of Nicola Bulley has told officers that she "doesn't know anything".
Mum-of-two Nicola, 45, disappeared a week ago as she walked her dog Willow along the River Wyre in the town of St Michaels, Lancashire.
The mortgage adviser's mobile phone as well as the lead and harness for her springer spaniel, Willow, were found on a bench close to the river.
