Farmers are being asked to help find a man who may be wild camping near Glastonbury or Wells.
Alan Stoles has been missing from his Bristol home since January.
He's 57 years old and described as white, about 5ft 10ins tall and stocky with short grey hair and a goatee beard.
His appearance may have changed from the photos above.
Officers now believe that Alan left his home in Bedminster Down, Bristol, on Thursday, January 21 and caught a bus to Wells.
From there he walked to Glastonbury, where he was seen in Fisher’s Hill the same afternoon.
He was carrying a rucksack and police believe that he may be wild camping.
He hasn’t responded to messages for friends or contacted work since January 19.
Friends reported him missing on January 23 after visiting his home and finding he’d left without personal property.
Avon and Somerset Police are asking farmers, dog walkers, riders and anyone else who visits open spaces and woodland in and around the area to let them know if they see Alan.
A spokesperson said: "Alan, if you see this message, please call 101 or get in touch with a friend.
"People care about you and are worried.
"We just want to know that you are safe and well or get you help if you need it."
If you have seen Alan recently, or have any information which could help to confirm that he is safe and well, call 101 quoting reference 5221016375.
