The body of a newborn baby has been found at a waste management site in Bradford.
The discovery was made last night by staff at the site on Valley Road.
The site processes material from homes in Leeds and Bradford. Enquiries are ongoing to determine where in West Yorkshire the baby may have come from.
A full post mortem examination is scheduled to take place later today to determine the cause of death but it is believed the child was only very recently born.
Officers are concerned for the health of mother.
My priority is the condition and welfare of the mother and ensuring she receives the medical care she needs.
The mother has clearly been through a terribly traumatic experience and I would ask her to come forward and speak to us.
Anyone with information is asked to contact the Homicide and Major Enquiry Team via: 101 or by calling Crimestoppers, anonymously and in confidence, on: 0800 555 111.
