The search is on for the owner of a pair of manky trainers, left side by side on a Norfolk beach.
A police psychologist has been studying the trainers with great interest and has come up with some interesting conclusions.
Norfolk Police told us: "They belong to a human being. They are worn on feet. Therefore they belong to someone who has legs & feet. The human who left these trainers obviously felt the need to take them off
"Thanks to the profile from our Psychologist we have ruled out the possibility of non humans, & the legless & those who have shoes on".
The witness who found the trainers gave this statement. "I was just wondering around the beach. I was not with anyone okay. I was alone. That other man is nothing to do with me whatsoever. I am a happily married woman. Anyhoo there I was wandering ALONE when I happened upon these trainers. I did not touch a thing. I knew to preserve the crime scene. Absolutely no one helped me call the police because I was alone"
The public have been advised not to approach any bare or socked feet humans. The person who owns these trainers may be deranged. Should anyone see anybody fitting the description, in or around the Norfolk area, please call someone and tell them about it.
