Thames Valley Police is continuing to appeal for information on the identity of this man (pictured) in relation to a missing person inquiry.
This photograph was taken by a member of the public in the Asda supermarket in Bletchley on Wednesday, August 21.
It is thought the picture could be of 62-year-old Brian Nolan, who was last seen in March 2013 in Tattenhoe.
Insp Yakoob Teladia from Milton Keynes police station said: “We are not sure if the man in these images is Mr Nolan, so we need whoever it is to come forward.
“If this is you, or you know who this is, please tell us immediately to help us in our enquiries to find Mr Nolan.
“And if you are Mr Nolan, please get in touch. We just need to know you are safe and well.”
Anyone with information can contact Thames Valley Police Enquiry Centre on 101.
