Police in England have renewed a public appeal for information after three human feet were discovered within a few hundred yards of each other.
The first foot was found in Weston Park East in Bath, Somerset, in February, the second was discovered in the garden of a property in Weston Park in July, and the third in the garden of a property in Cranwells Park earlier this month.
Avon and Somerset Police said the first foot was more than likely to be an exhibit from a medical or educational establishment and was not the result of a crime.
The force said it anticipated that inquiries into the second and third feet, which are still undergoing tests, are likely to come to the same conclusion.
Temporary Detective Inspector Paul Catton said: "We are confident no crime has been committed and strongly believe the feet have come from an old private collection.
"All three feet show signs they have come into contact with animals and it is likely that they have been moved to the locations they were found from a specific source.
"Regulations are significantly stricter these days compared to several decades ago and we believe the source is most probably someone who used the feet as a teaching aid.
"It is also possible these feet may have been found by someone who has then innocently buried them in an attempt to dispose of them and they have then been unearthed by animals, or that animals have disturbed the location they were stored.
"We believe someone knows something about where these feet have come from and would appeal for them to get in touch."
He added: "When the first foot was found, officers, along with cadaver dogs, carried out an extensive search of the immediate area.
"However, as we believe animals are moving these feet, we cannot be sure that nothing has been deposited in the area since and so we are rechecking.
"We are also now searching the rest of Weston Park East along with the grounds of the school.
"The school is in a central location to the sites were all three feet have been found and the last thing we want is for a member of the public to come across one of these unpleasant finds."
