“We would like to thank the members of the public who have already contacted us with information following our public appeals and we would urge anyone who was in the Monkton Park area on Sunday afternoon to cast their mind back – did you see a woman matching Fiona’s description on a mobility scooter? What direction was she heading in? Did anything appear out of the ordinary?

“Any information you have, no matter how small or insignificant it may seem, could be vital."

Anyone with information is urged to call Wiltshire Police on 101 and quote log number 342 of June 25.
