THE OFFICER leading the investigation into the disappearance of Sian O'Callaghan has thanked the public for their help but has asked that they stay away for the time being.

Det Supt Steve Fulcher said: "The enquiry moves on at a rapid pace with significant lines of enquiry being developed. The public have been fantastic in support of the search for Sian O Callaghan and I'm very grateful.

"I've beeen able to use new technological techniques to provide a tighter search parameter and have been able to rule out large areas of the 6 and a half mile radius we have all been searching.

"Those tactics are being urgently progressed today by specialists. I may need further support from the public closer to the weekend but for now I would ask that people monitor the force website, media and social networks for my further requests if they are required."
