Police investigating the death of a woman at a Shipley supermarket need the public's help to identify her.
The woman, aged between 20 and 40, stabbed herself in the throat shortly after 8.30am.
Officers were called to Asda, in Manor Lane, to reports of a woman being found with serious injuries. She was pronounced dead at the scene.
Police say a number of enquiries have been carried out to try and identify the woman, but so far have been unsuccessful.
The woman is described as having shoulder-length dark hair which was tied in a ponytail and she was wearing a dark blue top and trousers with large silver buttons to the front and a lighter blue or purple scarf.
Detective Inspector Ryan Bragg, of Bradford CID, said: "We have tried various means to identify this woman but as yet have not been able to do so.
"I would urge anyone who believes they may know the identity of this woman or who has concerns for a family member of friend who fits this description to make contact immediately.
"Anyone with concerns or information should call Bradford CID on 101."
The death is not being treated as suspicious and no one else is being sought in connection with the incident.
