A number of reported CCTV 'blindspots' have been identified as detectives continue to probe Nicola Bulley's disappearance.
The mum-of-two vanished while walking her dog by the river in St Michael's on Wyre, Lancashire, at around 9.10am on January 27.
Her phone was found on a bench by the waterside and had recently connected to a work call, while her dog Willow was running loose.
