Police are still searching for the owner of a severed foot two years after dog walkers found the body part.
The foot, believed by police to be female, was found on the path in New Waltham, North East Lincolnshire in April 2019.
Despite a long investigation and enquiries, Humberside Police say they are still yet to identify the owner of the foot.
Investigations included examination of processes for disposing body parts at Diana, Princess of Wales Hospital in Grimsby, which is several miles from where the foot was found.
There was also speculation at the time that a medical student may have obtained the foot as part of their homework and later disposed of it or a fox may have dug up the foot from a grave, but this was dismissed as Humberside Police officers said the foot and lower limb had been severed deliberately.
The force says it has carried out local, national, and international investigations into missing people, forensic testing and DNA analysis but are still yet to find a match.
They believe the foot could be a product of “medical waste” and are now appealing for any woman who has undergone an amputation to remove her left foot since 2014 to get in touch.
Officers and residents living nearby said they were baffled by the gruesome discovery, which was found by dog walkers in the early hours of April 25, 2019.
It fuelled fears in the local community that other body parts might be discovered and widespread searches were undertaken in the days after the discovery, but nothing else was ever found.
One New Waltham resident told GrimsbyLive at the time: “I was worried about going to our wheelie bin outside in case there was a body part disposed of in there.”
One of the dog walkers who found the foot said: “We were shocked but also relieved it was us that found it because the footpath is used by a lot of children going to school.
“Another hour and a child might have found it. So I am glad it happened when it did.”
Detective Chief Inspector Alan Curtis, Senior Investigating Officer in the case said on Wednesday: “A team of detectives have been working tirelessly to ascertain the identity of the individual and to determine how the body part came to be on the path.
“One line of our enquiry is that the foot may have been clinical waste from a medical procedure. This line of enquiry cannot be ruled out without a full and thorough investigation.
“Although this must seem a very strange request we are now appealing for any female in the Humberside Police Force area and Lincolnshire that has had a medical procedure to remove her left foot since 2014 to contact us.
“The NHS have been able to provide certain information in relation to hospital surgeries but this would not include any private medical procedures, so by issuing this appeal now we are hoping to rule out anyone within this category of patient.
“If you have had such a medical procedure in the past eight years whether through the NHS or through private medical services I would ask you to call us, your call will be treated with the utmost respect and privacy.”
Anyone who would be in that category of amputees or have information and have not yet spoken to the police are being asked to call 101 quoting log number 85 of April 25, 2019.
