A missing 71-year-old man from Fairford is thought to be in the Wiltshire area, police say.
Peter Harker has not been seen since yesterday morning, Thursday 5 December, and has not been in touch with family, which they say this is completely out of character.
Peter is described as being 6ft 4ins tall, has receding grey hair and stubble. He left home in a red Seat Ibiza, with the registration WM16 BLJ.
He was last seen wearing black jeans, a brown bomber jacket, beige canvas shoes and a dark sweatshirt.
A spokesperson for Glocstershire Constabulary said: “We think he has travelled to Wiltshire.
“We’re concerned for his welfare and asking for anyone who might have seen Peter, or his car, to call 101 and quote incident 268 of 5 December.”
