Police dogs and a helicopter discovered a body in Jubilee Crescent in Gorebridge, Midlothian, during the search for Tony Hutchison.

“We are working to formally identify the man, and ascertain the full circumstances of this, in order to provide answers to his family and the wider community.
“I’d encourage the local community to help us, wherever possible, and get in touch if they may have seen Tony, or captured him on any private CCTV, since the last confirmed sighting.
“Likewise, anyone who lives in the Arniston area and who may information relevant to our inquiries is urged to get in touch as soon as possible.”
Chief Inspector Arron Clinkscales added: “A number of local resources have been involved in the search for Tony, supported by national teams including the dog unit and the police helicopter, which has sadly led to a body being discovered.
“We fully appreciate the concern this will cause to the community, and want to reassure the public that there will be an increase in patrols to the Gorebridge area.
“Local officers will be supporting our colleagues in the MIT throughout their inquiries, and anyone with information is welcome to speak to any officer.”
