A police helicopter and search and rescue dogs are on the hunt for an 85-year-old man who's gone missing from his home in Sandybrook near Grantham.
John Setchell, who suffers from Alzheimers disease, was last seen at around 5pm yesterday when his carer visited him at home.
Lincolnshire Police believe he took his Jack Russell dog out for a walk, which was later returned to the man's house by a woman. Police are trying to trace her in the hope it will help them find Mr Setchell.
He was wearing a blue T-shirt, dark bottoms and possibly slippers when he went missing. Police want anyone with information to contact them.
