Detective Constable Adam Woolman, of Bournemouth CID, said: “During the course of an investigation police recovered a number of items from a second hand shop, including this arm.
“I believe this item may have been in a vehicle, either on or around 25 November.
“It is a Nasco Life/form Advanced Injection Arm and is used for the training of taking blood samples from patients.
“Enquiries have already been made with local hospitals.
“It is an unusual article and we hope that someone recognises it and can help us to find the rightful owner.
“Please contact us as soon as possible if you have any information that assists with my investigation.”
