Dozens of specially-trained volunteers were spotted searching Calne in a bid to locate Robert.
In a statement yesterday, Wiltshire Police said that Robert is living with dementia – but the force has since confirmed this information was incorrect.
A spokesperson said: “We are increasingly concerned about Robert’s welfare and would urge anyone with information about his whereabouts to get in touch.
“If you can help, call 101 or 999 in an emergency and quote log number 212 of today (28/7).”
